The answer is -3 because you’re plugging g(x) into f(x). For every x there is in f(x), plug in g(x)’s equation. After you get another equation (simplified), which is x^2 -7x -11, plug -1 for every x and condense.
you have to use intercept theorem, also known as Thales's theorem to slove this problem
x/9 = -6
Solve for X by multiplying both sides by 9:
x = -6 * 9
x = -54
A=hb*b/2
3yd*8yd= 24yd
now divide that by 2
12yards is the answer
The greatest common factor is 12w
