HURR FOR 25 POINTSSS Once simplified, which of the expressions below is equal to 2x+8? Select all that apply. A) 4(2x+8) B) 2(x+4) C) 3(3x+5)−7x–7 D) 6x–4–4x+4

B) 2(x+4)

C) 3(3x+5)−7x–7

Step-by-step explanation:

B) 2(x+4) = 2x + 8

C) 3(3x+5)-7x-7

= 9x +15 - 7x - 7

= 9x - 7x + 15 - 7

= 2x + 8

B and C

Step-by-step explanation:

1. B is one of the answers because when you distribute the 2, the expression simplifies to 2x+8.

2. (C) When you distribute the 3 through the parenthesis, the expression simplifies to 9x+15-7x-7. Next, subtract the like terms. 9x-7x=2x and 17-7=10. Now this simplifies the expression to 2x+8.
