Hello,

f(x)= \dfrac{4}{x-9} \\&#10;&#10;g(x)= \dfrac{4}{x+9} \\&#10;&#10;f(g(x))=f( \dfrac{4}{x+9} )\\&#10;&#10;= \dfrac{4}{ \dfrac{4}{x+9}-9} \\&#10;&#10;= \dfrac{4(x+9)}{4-9x-81} \\&#10;&#10;=- \dfrac{4x+36}{77x+9x} &#10;&#10;&#10;

How much material is used
Neko [114]
This question is essentially asking you to find the surface area of the box.
The formula for SA on a rectangular prism is: 2(L*W+L*H+W*H)
L=Length W=Width H=Height

Lets input the information we know:
2(20*8+20*30+8*30)
Follow BEDMAS
2(160+600+240)
2(760+240)
2(1000)
2*1000
=2000

The box will need 2000 centimeters squared of material.

Hope this helps!
