Respuesta :

It’s the last one -5n+16

Answer:

-5n + 16

Step-by-step explanation:

Distribute the 7 to the equation inside the parenthesis.

7(n + 1) - 12n + 9

7n + 7 - 12n + 9

Bring the -12n towards the 7n.

7n - 12n + 7 + 9

Add or subtract like terms.

7n - 12n + 7 + 9

  -5n     +   16  

Answer:

-5n + 16
