Commutative property of addition
Step-by-step explanation:
Commutative property of addition states that if a and b are any two elements
then, a + b = b + a
We are given a equality we have to determine the property used here
5x · (4y + 3x) = 5x · (3x + 4y)
In the above equation, 4y + 3x = 3x + 4y
a= 4y and b= 3x
Then, a+b=b+a
Hence, the property used above is:

What is larger: The height of a standard can of tennis balls, or the circumference of its lid?
(Assume the can fits three tennis balls perfectly). Explain your reasoning. ...?
Final answer:
The height of a can holding three tennis balls is 20.1 cm, while the circumference of the lid is approximately 21.02 cm. Hence, the circumference of the can's lid is slightly larger than its height.
Explanation:
The question is comparing two different measurements of a can that holds tennis balls. One measurement is the height of the can, and the other is the circumference of the can's lid. In a standard can of tennis balls, three tennis balls are stacked on top of each other perfectly. Knowing that the diameter of a standard tennis ball is approximately 6.7 cm, we can calculate the height of the can by multiplying the diameter of one tennis ball by three (since the diameter is the same as the height for a ball stacked in such a can).
Height of can = Diameter of tennis ball × number of balls
= 6.7 cm × 3
= 20.1 cm.
To determine the circumference of the can's lid, we first need to find the radius of the lid which would be half the diameter of a tennis ball:
Radius of lid = Diameter of tennis ball / 2
= 6.7 cm / 2
= 3.35 cm.
Then, we use the formula for the circumference of a circle, which is C = 2πr:
Circumference of lid = 2π × Radius of lid
= 2π × 3.35 cm
≈ 21.02 cm.
The circumference of the lid is slightly larger than the height of the can. Therefore, the circumference of the can's lid is larger than the height of the can of tennis balls.

How would i find the rule for this pattern:1280,640,320,160?
The rule for this pattern is to divide each number by 2 to get the next number.
Explanation:To find the rule for this pattern, we need to identify the relationship between the numbers. In this case, each number is half of the previous number. So, to find the next number, we divide the previous number by 2.
For example, 640 is half of 1280, 320 is half of 640, and so on. This means that to find the next number, we divide 320 by 2 to get 160.
Therefore, the rule for this pattern is to divide each number by 2 to get the next number.

1. What is the sum of the polynomials?
(m + n + 3) + (m + n + 4)
2. Find the difference of the polynomials
(10m – 6) – (7m – 4)
3. Find the difference of the polynomials
(4m – 5) – (6m – 7 + 2n)
Answer:
1. 2m+2n+7
2. 3m-2
3.-2m+2-2n
Explanation:
To find the sum of given polynomials (m+n+3) +(m+n+4)
Firstly, open the parenthesis we will get m+n+3+m+n+4
After simplification we will get 2m+2n+7
To find the difference of given polynomials (10m-6)-(7m-4)
Firstly, open the parenthesis we will get 10m-6-7m+4
After simplification we will get 3m-2
Again to find the difference of the polynomials (4m-5)-(6m-7+2n)
Firstly, open the parenthesis we will get 4m-5-6m+7-2n
After simplification we will get -2m+2-2n
The sum of the polynomials (m + n + 3) and (m + n + 4) is 2m + 2n + 7. The difference of the polynomials (10m – 6) and (7m – 4) is 3m - 2. The difference of the polynomials (4m – 5) and (6m – 7 + 2n) is -2m - 2n - 2.
Explanation:To find the sum of the polynomials (m + n + 3) and (m + n + 4), we simply combine like terms:
(m + n + 3) + (m + n + 4)
= m + m + n + n + 3 + 4
= 2m + 2n + 7.
To find the difference of the polynomials (10m – 6) and (7m – 4), we subtract the second polynomial from the first:
(10m – 6) – (7m – 4)
= 10m - 7m - 6 + 4
= 3m - 2.
Lastly, to find the difference of the polynomials (4m – 5) and (6m – 7 + 2n), we again subtract the second polynomial from the first:
(4m – 5) – (6m – 7 + 2n)
= 4m - 6m + 5 - 7 - 2n
= -2m - 2n - 2.

Which of the following is equivalent to log base 9 27 ?
Which of the following is equivalent to log base 9 27 ?
The equivalent of log base 27 of 9 is 2/3, as 27^(2/3) equals 9.
Thus, the correct answer is b. 2/3 among the provided choices.
To find an equivalent expression for log base 27 of 9, we need to determine the exponent to which 27 must be raised to obtain 9. In other words, we want to find x in the equation 27^x = 9.
Recognizing that 27 is 3^3 (as 3 times 3 times 3 equals 27), we can rewrite the equation as (3^3)^x = 9. Applying the exponent rule (a^b)^c = a^(bc), this simplifies to 3^(3x) = 9.
Now, equating the exponents, 3x = 2 since 3^2 equals 9. Solving for x, we find x = 2/3. Therefore, log base 27 of 9 is 2/3.
Among the provided choices:
a. 1/3
b. 2/3
c. 3/2
d. 0.798
The correct equivalent is b. 2/3, as it matches the determined value of log base 27 of 9.
The question probable may be:
Which of the following is equivalent to log27 9?
answer choices:
a 1/3
b 2/3
c 3/2
d 0.798
The equivalent of log base 27 of 9 is 2/3, as 27^(2/3) equals 9.
Thus, the correct answer is b. 2/3 among the provided choices.
We must ascertain the exponent to which 27 must be raised in order to
achieve 9 in order to discover an analogous formula for log base 27 of 9.
Put otherwise, we wish to determine x in the formula 27^x = 9.
Since 3 times 3 times 3 is 27, we may express the equation as (3^3)^x = 9 since we know that 27 is 3^3.
Applying the exponent rule (a^b)^c = a^(bc), this simplifies to 3^(3x) = 9.
Now, equating the exponents, 3x = 2 since 3^2 equals 9.
Solving for x, we find x = 2/3. Therefore, log base 27 of 9 is 2/3.
Among the provided choices:
a. 1/3
b. 2/3
c. 3/2
d. 0.798
The correct equivalent is b. 2/3, as it matches the determined value of log base 27 of 9.

The sum of three consecutive odd integers is -27. What are the numbers?
The three consecutive odd integers are [tex]-11, -9,[/tex] and [tex]-7[/tex].
To find three consecutive odd integers whose sum is -27, let's define the three integers as follows:
Let the first consecutive odd integer be [tex]x[/tex].The second consecutive odd integer will be [tex]x + 2[/tex].The third consecutive odd integer will be [tex]x + 4[/tex].According to the problem, the sum of these integers is -27. We can write this as an equation:
[tex]x + (x + 2) + (x + 4) = -27[/tex]
Now, let's simplify and solve the equation step-by-step:
Combine like terms on the left-hand side of the equation:
[tex]x + x + 2 + x + 4 = -27[/tex]
[tex]3x + 6 = -27[/tex]
Subtract 6 from both sides to isolate the term with [tex]x[/tex]:
[tex]3x + 6 - 6 = -27 - 6[/tex]
[tex]3x = -33[/tex]
Divide both sides by 3 to solve for [tex]x[/tex]:
[tex]x = \frac{-33}{3}[/tex]
[tex]x = -11[/tex]
So, the first consecutive odd integer is [tex]-11[/tex].
Find the second consecutive odd integer:
[tex]-11 + 2 = -9[/tex]
Find the third consecutive odd integer:
[tex]-11 + 4 = -7[/tex]

A farmer wants to build a pen for his sheep. One side of the pen will be a river. The sheep need about 2000 m2 of area to graze. About what length (x) and width (y) should the organization use to use the LEAST amount of fencing possible?
A) length = 43 m, width = 46 m
B) length = 50 m, width = 40 m
C) length = 63 m, width = 32 m
D) length = 100 m, width = 20 m
The option closest to [tex]\( x = 10\sqrt{10} \) and \( y = 200\sqrt{10} \)[/tex] is option D) length = 100 m, width = 20 m. So, the answer is option D.
To minimize the amount of fencing needed, we want to maximize the area of the pen while fulfilling the requirement of 2000 m².
Let's denote the length of the pen as x and the width as y. Since one side of the pen is a river, we only need to fence three sides: two sides of length x and one side of length y. So, the total fencing required is 2x + y.
We're given that the area of the pen should be 2000 m², so we have the equation:
xy = 2000
We want to minimize 2x + y. We can solve the area equation for one variable and substitute it into the expression for the fencing:
[tex]\[ y = \frac{2000}{x} \][/tex]
Substitute this expression for y into the expression for the fencing:
[tex]\[ \text{Fencing} = 2x + \frac{2000}{x} \][/tex]
To minimize this expression, we can take its derivative with respect to x, set it equal to zero, and solve for x.
[tex]\[ \frac{d}{dx}(2x + \frac{2000}{x}) = 2 - \frac{2000}{x^2} = 0 \][/tex]
[tex]\[ 2 = \frac{2000}{x^2} \][/tex]
[tex]\[ x^2 = \frac{2000}{2} = 1000 \][/tex]
[tex]\[ x = \sqrt{1000} = 10\sqrt{10} \][/tex]
Once we find x, we can find y using the area equation:
[tex]\[ y = \frac{2000}{x} = \frac{2000}{10\sqrt{10}} = 200\sqrt{10} \][/tex]
Now, we need to choose the option closest to x and y.
Checking the options:
A) length = 43 m, width = 46 m
B) length = 50 m, width = 40 m
C) length = 63 m, width = 32 m
D) length = 100 m, width = 20 m
The option closest to [tex]\( x = 10\sqrt{10} \) and \( y = 200\sqrt{10} \)[/tex] is option D) length = 100 m, width = 20 m.
So, the answer is option D.

Which is a secant of circle A?
(Points : 1)
segment AB
line DE
segment HG
line CD
Answer:
The correct option is line CD
Step-by-step explanation:
Given the diagram we have to find the secant of circle A.
Secant of a circle is a line intersecting the circle at exactly two different points and a chord is the line determined by these two.
In the circle A the only line intersect two different points is CD and the interval on a secant is the chord of circle.
Here, HG is only the chord of circle not secant.
Hence, the correct option is line CD
