    9c + (8+3c)

    9c+8+3c (collect like terms)

    9c+3c+8

    12c+8

    12c+8 is the answer.

    im not sure if your teacher also wants the answer to be in simplest form so im going to do that below as well:

    12c+8 (4*3=12 and 4*2=8. you can take out a 4 from those 2 numbers)

    4 (3c+2) (this is the simplest form of 9c + (8+3c))
