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

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

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

• Math 012 -

-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)

okay thanks.

-4(4+2p+5)+16
-16-8p-20+16
-16-8p-4
-12-8p

Okay so you totally owned me, great job checking.
Go order of operations!!!

• Math 012 -

no. The last step is wrong
-16-4 is -20
