Question

Ho do I put this into a simpler expression

Answer 1

2n + 2.

You perform the appropriate acts for the ones that should be grouped together like the regular numbers and the n's.

Answer 2

The instruction is right there ! "COMBINE THE LIKE TERMS". That means ==> add up all the 'n' terms and make a single 'n' term, then ==> add up all the plain numbers to make a single plain number.
