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

-4(4+2p+5)+16

-16-8p-20 +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)
