9(2j + 7 + 5j). Use either the commutative property or combine like terms to create an equivalent expression.

your answer is 63j+63.

Step-by-step explanation:

as i said before, this is your answer.

step 1: collect like terms. (add 7j and 5j because they are like terms.)

9(2j+7+5j)

9(7j+7)

9(7j+7) =

63j+63
