F(x)=(x-8)/(x+7). g(x)=(-7x-8)/(x-1). Plug in g(x) into f(x), f(g(x))=[(-7x-8)/(x-1)-8]/[-7x-8)/(x-1)+7], which can be simplified as (-7x-8-8x+8)/(-7x-8+7x-7)=-15x/-15=x. Plug in f(x) into g(x), g(f(x))=[-7*(x-8)/(x+7)-8]/[(x-8)/(x+7)-1]=(-7x+56-8x-56)/(x-8-x-7)=-15x/-15=x, as desired.
Answer: Volume is 15cm
Step-by-step explanation: for ever square add 1/2 to each other
Perimeter is adding up all of the sides
the top and bottom are 3 and the left and right 10
so top (3)+ bottom (3)+ left (10)+ right(10)
3+3+10+10= 26
So your answer is c 26units
