ANSWER

EXPLANATION
The volume of a rectangular prism is given by the formula,

We substitute the dimensions to obtain,

The volume of the rectangular pyramid is,

Equating the two volumes gives,

We divide through by 6×12 to get,

We solve for x to obtain,

Answer:
answer B 
Step-by-step explanation:
f(8)=-2*8+5=-11
g(8)=9*8*8+4=580
f(8)+g(8)= -11+580=569
Divide 636 / 12 which equals 53 ?

Step-by-step explanation:
Answer:
x=1
Step-by-step explanation:
So we are talking about parabola functions.
All parabolas (even if they aren't functions) have their axis of symmetry going through their vertex.
For parabola functions, your axis of symmetry is x=a number.
The "a number" part will be the x-coordinate of the vertex.
The axis of symmetry is x=1.
