Answer: (7x^2+144)/x^2
Step-by-step explanation:
f(h(x))=
f(12/x)=
(12/x)^2+7=
12^2/x^2 + 7=
144/x^2 +7=
144/x^2 +7*x^2/x^2=
144/x^2+7x^2/x^2=(7x^2+144)/x^2
Distribute 4 with x and 2 to get the equation 3x+2=x+4x+8. Combine x and 4x to get 5x. Minus 3x from each side. Now you should have 2=2x+8. Subtract 8 from both side to get -6=2x. Divide and you get x=-3
