Answer:
870 calories Option D.
Step-by-step explanation:
A bag of chips contains calories per serving = 145
If each bag contains servings = 3
so total calories per bag = 3 × 145
= 435
Now we have to calculate the total servings in 2 bags.
Number of calories in 1 bag = 435
Therefore, number of calories in 2 bags = 435 × 2
= 870 calories
Option D. 870 calories is the answer.

Answer:
Answer is
[tex]x^3-7x^2+17x-20 \\ [/tex]
Step-by-step explanation:
We need to find
[tex](x-4)(x^2-3x+5) \\ [/tex]
Using distribution rule.
[tex](x-4)(x^2-3x+5)=x^3-4x^2-3x^2+12x+5x-20\\\\(x-4)(x^2-3x+5)=x^3-7x^2+17x-20 \\ [/tex]

For f(x) = 2x + 1 and g(x) = x2 – 7, find (f – g)(x).
A. –x2 + 2x – 6
B. 2x2 – 15
C. x2 – 2x – 8
D. –x2 + 2x + 8
HELP!! give me the correct answer
For the function, f(x) = 2x + 1 and g(x) = x² – 7, (f – g)(x) will be D. –x² + 2x + 8
How to calculate the functionTo find (f - g)(x), we need to subtract the function g(x) from the function f(x).
f(x) = 2x + 1
g(x) = x² - 7
(f - g)(x) = f(x) - g(x)
Substituting the given functions:
(f - g)(x) = (2x + 1) - (x² - 7)
Now let's simplify:
(f - g)(x) = 2x + 1 - x² + 7
Combining like terms, we have:
(f - g)(x) = -x² + 2x + 8
Therefore, the answer is D. -x² + 2x + 8.

What is the lcm of 21, 84, 126?
Fill in the missing number to complete the factorization:
x 3 + x 2 - 21x - 45 = (x + 3)(x - 5)(x +
Missing number to complete the factorization is 3.
What is factorization?Factorization can be defined as the process of breaking down a number into smaller numbers which when multiplied together arrive at the original number. These numbers are broken down into factors or divisors.
Given expression
[tex]x^{3}+x^{2} -21x-45=(x+3) (x-5) (x+a)[/tex]
Let a be the missing number
(x + 3) (x - 5) (x + a)
= [tex](x^{2} -5x+3x-15)(x+a)[/tex]
= [tex](x^{2} -2x-15)(x+a)[/tex]
[tex]x^{3}+x^{2} -21x-45=x^{3} +x^{2} a-2x^{2} -2xa-15x-15a[/tex]
By comparing the expressions
-2xa - 15x = -21x
⇒ -2xa = -6x
⇒ a = 3
[tex]x^{2} (a-2) = 1x^{2}[/tex]
⇒ a - 2 = 1
⇒ a = 3
-15a = -45
⇒ a = 3
Hence, missing number to complete the factorization is 3.

Tina has to pay 4 percent of the purchase price toward closing costs for her mortgage. If the purchase price is $275,000, what is the closing cost amount?
Answer:
Proportion states that two fractions or ratios are equal.
Let x be the closing cost amount.
As per the statement:
Tina has to pay 4 percent of the purchase price toward closing costs for her mortgage. If the purchase price is $275,000.
Purchased Price = $275,000
then, by definition of proportion :
[tex]\frac{4}{100}=\frac{x}{275000}[/tex]
By cross multiply we have;
1,100,000 = 100x
Divide both sides by 100 we have;
11,000 = x
or
x = $ 11,000
Therefore, the closing cost amount is, 11,000
Determine whether the dilation from A (blue figure) to B (green figure) is an enlargement or reduction, then find the scale factor of the dilation.
a. reduction; scale factor of 2/5
b. enlargement; scale factor of 5/2
c. reduction; scale factor of 2/3
d. enlargement; scale factor of 3/2
Answer:
Option B
Step-by-step explanation:
In the figure attached we have to find the scale factor of dilation of figure A to figure B.
Since figure A is smaller than figure B, it concludes figure A has been enlarged to form figure B.
Now we have to find the scale factor of enlargement.
Scale factor = [tex]\frac{\text{one side of the larger figure}}{\text{one side of the smaller figure}}[/tex]
= [tex]\frac{5}{2}[/tex]
Therefore option B is the correct answer.

15. TRIANGLES Find the dimensions of a triangle if the base is 2/3 the measure of the height and the area is 12 square centimeters. (Lesson 4-3)
The dimensions of the triangle with a base that is 2/3 of its height and an area of 12 square centimeters are a base of 4 centimeters and the height of 6 centimeters.
Explanation:The question asks for the dimensions of a triangle. We are given that the base is 2/3 of the height and the area is 12 square centimeters. The formula for the area of a triangle is 1/2 * base * height. Since we know that the base is 2/3 of the height, we can denote the height as 'h' and the base as (2/3)h. From here, we can set up the equation 12 = 1/2 * (2/3)h * h, which simplifies to 12 = 1/3 * h². Solving for 'h', we find the height is √36 or 6 centimeters. Given the base is 2/3 of the height, the base, therefore, is 4 centimeters.

What step in the construction of copying a line segment ensures that the new line segment has the same length as the original line segment?
To copy a line segment and ensure it has the same length as the original, use a compass to measure and create a duplicate line segment.
Explanation:To copy a line segment and ensure that the new line segment has the same length as the original, we can use a compass. Here are the steps:
Place the compass needle on one endpoint of the original line segment.Open the compass to the length of the original line segment.Without changing the compass width, place the compass needle on the other endpoint of the original line segment and draw an arc.Use the compass to measure the same length on the arc and draw a line segment connecting the two marks.By using this method, we can create a duplicate line segment with the same length as the original.
