Answer:

b. 5n + 30 = 2n - 2

Explanation:

The distributive property requires the outside factor be applied to every term inside parentheses. After eliminating parentheses using the distributive property, terms can be collected on the right.

5(n +6) = 2(n -3) +4

5n +5·6 = 2n +2(-3) +4

5n + 30 = 2n -6 +4

5n + 30 = 2n - 2 . . . . . matches choice B
