Final answer:
To find x when g(x) = -52, substitute -52 for g(x) in the equation and solve for x. The correct answer is A. x = 20.
Step-by-step explanation:
To find x when g(x) = -52, we need to substitute -52 for g(x) in the equation -3x + 8 = -52.
-3x + 8 = -52
Subtract 8 from both sides: -3x = -60
Divide both sides by -3: x = 20
Therefore, the correct answer is A. x = 20.
