Which expression is NOT equivalent to the other three? A) - 9 - 7n + 16n B) 9 (n - 9) Eliminate C) n - 9 + 8n D) 9n - 9

The expression is not equivalent to other three is 9 (n-9).

Option (B) is correct.

Step-by-step explanation:

Take first expression

= - 9 - 7n + 16n

= 9n-9

Take second expression

= 9 (n-9)

= 9 * n - 9 * 9

= 9n - 81

Take third expression

= n-9+8n

= 9n-9

Take fourth expression

= 9n-9

Therefore expression is not equivalent to other three is 9 (n-9).

Option (B) is correct.
