Seeing as how the question was answered already by the teacher above, I'll provide a calculator answer to the question with some explanations.

Your question: 3(3x^2 + x - 5)

= 3* (3x^2 + x -5)

by distributive property, you multiply 3 to all 3 the coefficients and constant.

A: 9x^2 + 3x - 15

On an SAT reasoning test, you might be asked to find the value of x (given that the question provided is in equation form) and knowing how to solve questions such as this one is the first step to solving actual test questions.
