Question

Which expression is NOT equivalent to the other three?

Answer 1

Answer:

9(n - 9)  = 9n - 81

Step-by-step explanation:

Equivalent expressions are expressions which are equal . To determine if expressions are equivalent, simplify to lowest terms through combining like terms.

-9 - 7n + 16n  =  -9 + 9n

9(n - 9)  = 9n - 81

n - 9 + 8n  = -9 + 9n

9n - 9 = -9 + 9n
