I need help with this one too, same thing. Rewrite without parerntheses, then simplify if possible.

You do it, I will stay around for awhile and check you.

168p20 +16
take 4 times 4 which equals 16
take 4 times 2p which equals 8p
take 5 times 4 which equals 20
then add 16 to the end.
simplify by adding 16, 20 and 16.
you get 8p  20 (the 16 and +16 cancel each other out)
