Answer:
4c - 2
Step-by-step explanation:
Add up all the terms to find the perimeter.
2c + 2(c - 1)
2c + 2c - 2
4c - 2
Therefore, the perimeter is 4c - 2.
Answer:
The total surface area is: 468 in^2 which agrees with answer a)
Step-by-step explanation:
The three lateral faces of the prism are rectangles, and the sums of their areas give:
12 * 10 + 9 * 10 + 15 * 10 = 360 in^2
The area of each triangular base (notice it is a right triangle) is given by:
9 * 12 / 2 = 54 in^2, so we add TWO of these to the three rectangular faces:
Total surface = 360 in^2 + 2 * 54 in^2 = 468 in^2
Answer:
-10
Step-by-step explanation:
Let x = number
10 less than a number is the same number doubled
x-10 = 2x
Subtract x from each side
x-10-x = 2x-x
-10 = x
The number is -10
Answer:
A: f(x)=2x^2 +12x +10
B: f(0) = 10
Step-by-step explanation:
<u>Part A</u>:
f(0) is a constant in the equation if the form is such that for x=0, all terms are zero except one of them. Standard form is one such form. This is the equation in standard form:
f(x) = 2x^2 +12x +10
__
<u>Part B</u>:
f(0) = 0 + 0 + 10
f(0) = 10
Answer:
4 
<em><u>OR</u></em>
<em><u /></em>
<em><u /></em>
Step-by-step explanation:
<em><u>I'm not exactly sure which type of fraction you're asking for, so I'll put both.</u></em>
This would be the fraction for 4.5 because the 0.5 is half of 1, while we already have a whole number, being 4.
<em><u>OR</u></em>
9 divided by 2 is 4.5, making the fraction for 4.5,
