Question

Once simplified, which of the expressions below is equal to −3x−39? Select all that apply.

Answer 1

It would be B. When you apply the distributive property (which is multiplying the outside integer on the outside of the parenthesis by the ones one the inside) you get -3 times x, which is -3x, and -3 times 13, which is -39 (it is negative because the positive times the negative is negative). This results in the solution -3x-39.
