The answer is simple. Since g(x) is already in the equation 9x^3+2x^2, we know that if fg(x))-g(x) must equal f(x). If x-x=0, then 5x^3-7x+4-5x^3-7x+4. Yet if we simplify, we have the answer 8. So your final answer will be 9x^3+2x^2+8.

Answer:
The enlargement will be 30 ft by 7.5 ft.
Step-by-step explanation:
A scale drawing is a larger or smaller version of an object. To find the dimensions of the new drawing, multiply each measurement by the scale factor. The scale factor here is 5/2 or 2.5.
12(2.5)=30 ft
3(2.5)=7.5 ft
Sin(A)/a= sin(C)/c, therefore sin(A) would = asin(C)/c= sin(35deg)/2. So, A then = arc sin(sin(35deg)/2)= 16.67
