Answer:
A
Step-by-step explanation:
Step 1, setting variables:
We already know the <em>exact</em> height of the prism: 6 feet. We can set the unknown width as variable <em>x</em>, and length as <em>x+2 </em>(<u>length is two feet more than width</u>).
Step 2, writing equations:
Great! We have everything now. Let us write the equation by<u> substituting our variables in</u>:

Ok! Let us <u>expand</u> the equation:
<u />

Answer:
3^x -2x +14
Step-by-step explanation:
I will assume you mean 3^x in the function f(x)
f(x) = 3^x+ 10
g(x) = 2x - 4
(f - g)(x) = 3^x+ 10 - (2x - 4)
Distribute the minus sign
= 3^x+ 10 - 2x + 4
= 3^x -2x +14
