Answer:
the ratio of the surface area of Pyramid A to Pyramid B is:
Step-by-step explanation:
Given the information:
- Pyramid A : 648
- Pyramid B : 1,029
- Pyramid A and Pyramid B are similar
As we know that:
If two solids are similar, then the ratio of their volumes is equal to the cube
of the ratio of their corresponding linear measures.
<=>
=
=
= 
<=> 

Howver, If two solids are similar, then the
n ratio of their surface areas is equal to the square of the ratio of their corresponding linear measures
<=>
=
So the ratio of the surface area of Pyramid A to Pyramid B is:
28
3/7 = 12/x
x = (12*7)/3
x = 84/3
x = 28
Hello,
Answer B
f(g(x))=f(x²-7x-9)=x²-7x-9-2=x²-7x-11
f(g(-1))=1+7-11=-3
