Answer:
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
Answer:
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.
