Answer:  Choice B

Explanation:

Choice A simplifies to 9n-8 after combining the like terms -7n+16n to get 9n

Choice C simplifies to 9n-8 for similar reasoning. The n+8n turns into 9n

This shows choices A and C are equivalent to choice D. Choice B isn't the same because 9(n-8) = 9n-9*8 = 9n-72. Use the distributive property.

Answer:

B. 9(n - 8)

Step-by-step explanation:

- 8 - 7n + 16n

-8 (-7n + 16n or 16n - 7n)

-8 + 9n

9n - 8

9(n - 8)

9n - 72

n - 8 + 8n

9n - 8

9n - 8
