Answer: Find the surface area with the formula 
Step-by-step explanation:
<u><em> Since you did not provide the figure, I will give you a general explanation about how to solve this exercise.</em></u>
By definition, the surface area of a rectangular prism can be calculated with the formula shown below:

Where "SA" is the surface area of the rectangular prism, "w" is the width of the rectangular prism, "l" is the length and "h" is the height of the rectangular prism.
Therefore, if you know the length, the width and the height of the rectangular prism, you can follow these steps in order to calculate how much glass was used to make the tank. The procedure is:
Step 1: You must substitute the values of "l", "w" and "h" into the formula.
Step 2: Finally, you must evaluate in order to get the surface area of the rectangular prism (This value is the amount of square inches that was used to make the tank).

V(cylinder) = PR(squared)H
8 squared is 64pi
times 55 is 3520
Carter- 20+10=30+(5x4)=50+2=$52
Aubrey- 10x2=20+(5x5)=45+7=$52
They both have the same amount of money
Answer:
c
Step-by-step explanation:
x^2+5x-14
factor by finding multiples of (-14) that add up to 5
7*-2=-14
7+-2=5
So the factored out equation is (x+7)(x-2)
Therefore the solutions are x=-7 and x=2
