Answer: I believe the answer would be 64w2.
Step-by-step explanation: 8 squared is 8 x 8, which equals 64, and then w squared is just w2, since we don't know what it is. Put them together, and the answer is 64w2.

What is the first step when rewriting y=3x^2 +9x-18 in the form y=a(x-h)^2 +k?
ANSWER
3 must be factored from 3x² +9x
EXPLANATION
The given function is
[tex]y = 3 {x}^{2} + 9x - 18[/tex]
To write the given function in vertex form, we need to complete the square.
But before we come complete the square, we must ensure that the coefficient of the quadratic term is unity.
Hence we factor 3 from 3x² +9x to obtain:
[tex]y = 3( {x}^{2} + 3x) - 18[/tex]
The first choice is correct.
The first step to rewrite the equation y=3x^2 + 9x - 18 in the form y=a(x-h)^2 + k is to complete the square.
Explanation:The first step to rewrite the equation y=3x^2 + 9x - 18 in the form y=a(x-h)^2 + k is to complete the square. To do this, we need to factor out a from the quadratic term:
y=3(x^2 + 3x) - 18
Next, we take half of the coefficient of x (which is 3) and square it to find h:
h = (3/2)^2 = 9/4
Now, we add this value inside the parentheses and subtract it outside:
y=3(x^2 + 3x + 9/4) - 18 - 9/4
Simplifying further, we get:
y=3(x + 3/2)^2 - 81/4
So, the equation y=3x^2 + 9x - 18 can be rewritten in the form y=a(x-h)^2 + k as y=3(x + 3/2)^2 - 81/4.

The lengths of the sides of a right triangle are 10in, 24in, and 26in. What is the area of the triangle?
The area of a right triangle with legs of 10in and 24in is 120 square inches, calculated using the formula Area = 0.5 * base * height.
Explanation:The area of a right triangle can be calculated using the formula:
Area = 0.5 * base * height
In this case, the base and height can be taken as the two legs of the right triangle. Given the lengths of the legs as 10in and 24in, the area can be calculated as:
Area = 0.5 * 10in * 24in = 120 square inches
What is the perimeter of the trapezoid 10 POINTS
Answer:
19 units
Step-by-step explanation:
There are two sides that are equal; they are 4 units long.
The unequal sides are 7 and 4 in length.
Add up these four sides to obtain the perimeter:
P = 4 + 4 + 4 + 7 = 19 units
The perimeter of a figure is the distance around the figure.
To find the perimeter of the trapezoid shown, we can simply add the sides. Each square represents 1 unit.
Once we count each square that has a line through it, we will get
7 + 4 + 4 + 4 = 19
Therefore, the perimeter of the trapezoid is 19 units.

So if you distribute 4 in the first parentheses, you get 12x+20y+8z.
Then you distribute 3 in the second parentheses. You'll get 3x-3z. That all equals 12x+20y+8z+3x-3z.
Now you have to start combining numbers with the same variable. Start with x. 12x+3x is 15x.
y has no other common variable, it's left alone.
8z-3z is 5z
All together now with the numbers in simpler form, the equation is 15x+20y+5z
Jenna's would be the right answer because when you distribute 5 in her answer you get 15x+20y+5z

Six out of the 114 elements are noble gases. You write the names of all the elements on cards and select a card at random. What is the probability of not picking a noble gas?
Answer:
18/19 = About 95%
Step-by-step:
If only six are noble gases, 108 are not noble gases.
114-6= 108
So, the probability of not picking a noble gas is 108 out of 114. This simplifies to 18/19 which is about 95%.
When constructing an inscribed polygon with a compass and straightedge ,how should you start the construction?
Place a point on your paper and then use a compass to construct a circle.
Answer with explanation:
To construct an inscribed polygon with a compass and straightedge:
The first step is:
1.⇒Draw the polygon either it is Regular or Irregular
→A polygon is said to be regular, if it's all sides and all Interior Angles are equal.
→Draw the perpendicular bisector of all the sides of Polygon.
→The point where these two perpendicular bisector meet is center of the circle.
→Draw the circle which will pass through all the vertices of the Polygon you have drawn.
A 3cm x 2cm rectangle sits inside a circle with radius of 4 cm. What is the area of the shaded region? Round your final answer to the nearest hundredth.
Answer:
The area of the shaded region is [tex]44.24\ cm^{2}[/tex]
Step-by-step explanation:
we know that
The area of the shaded region is equal to the area of the circle minus the area of rectangle

Find the area of circle
The area of the circle is equal to
[tex]A=\pi r^{2}[/tex]
we have
[tex]r=4\ cm[/tex]
substitute
[tex]A=\pi (4)^{2}[/tex]
[tex]A=16\pi\ cm^{2}[/tex]

What are the excluded values of x for 2-3x-28/х2-2x-35
х= -7, x= 4
x=-7, х = 5
x=-5, х = 7
х= 4 х=7
Answer:
C
Step-by-step explanation:
The excluded values are the values of x that make the denominator of the rational function equal to zero as this would make the function undefined.
Equate the denominator to zero and solve for x to obtain the values that x cannot be.
x² - 2x - 35 = 0
(x - 7)(x + 5) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 7 = 0 ⇒ x = 7
x + 5 = 0 ⇒ x = - 5
Excluded values of x are x = - 5, x = 7 → C

A. The probability of randomly not choosing a black pen is 5/6 or about 0.83 (there are five other colors).
B. The probability of randomly choosing a black pen is 1/6 or about 0.17 (only one black pen out of six).
C. The probability of randomly choosing a red or blue pen is 2/6 or about 0.33 (two desired colors out of six).
D. This is correct because The probability of randomly choosing an orange pen is 1/6, which rounds to about 0.17.
E. The probability of randomly not choosing a purple or blue pen is 4/6 or about 0.67 (four other colors), so this is correct.
F. The probability of randomly choosing a green or red pen is 2/6 or about 0.33 (not 0.5 as stated).

a ladder that is 26 feet in length touches a house at a height of 24 feet from the ground. how far from the house is the base of the ladder?
The house is 10 units far from the base of the ladder?
What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that
length of ladder = 26 feet
And height of house = 24 feet
According to given scenario it will form a right angled triangle.
In which the length of ladder is hypotenuse
Height of house be perpendicular
And base we have to calculate.
We know that the Pythagoras theorem for a right angled triangle:
(Hypotenuse)²= (Perpendicular)² + (Base)²
Now plug the values
(26)²= (24)² + (Base)²
(26)²= (24)² + (Base)²
676 = 576 + (Base)²
(Base)² = 100
Base = 10 units
Thus, the base is of 10 units.

What quadratic has roots x=8 and x= -5
Answer:
The quadratic function x^2 -3x + 40 has roots x=8 and x= -5.
Step-by-step explanation:
If a polynomial has roots x=8 and x=-5, then we know that the factorized form is:
(x-8)(x+5)
So, to find the polynomial we need to expand the polynomials:
(x-8)(x+5) = (x^2 +5x - 8x + 40) = x^2 -3x + 40
Answer:
x² - 3x - 40 = 0
Step-by-step explanation:
The roots are x=8 and x= -5
The quadratic equation will be;
(x-8)(x+5) = 0
Therefore;
x² - 8x + 5x -40 = 0
x² - 3x - 40 = 0
