The answer is 18...
(3 / 8 ) * 48 = 18
(f+g)(x)=f(x)+g(x)= 3x+5 + (-2x^2-5x+3) = -2x^2 -2x+8 (B)
Answer: first option.
Step-by-step explanation:
The formula you must use to calculate the volume of the figure shown is the following:

Where B is the area of the base and H is the height.
Assuming that the base of the pyramid is a square, you have that B is:

Substitute values into the formula, Then you obtain:

Answer:
1/9
Step-by-step explanation:
after simplifying you will get 3^b-a. if a-b =2, b-a=-2. 3^-2=1/9
