Question

2p - 6(2p + 2) + 2(5p - 5) - 3(3p - 5)

A) -84p - 8
B) -9p - 7
C) -84p - 7
D) -9p - 8

Answer 1

You have to expand first, so:
2p - 6(2p + 2) + 2(5p - 5) - 3(3p - 5) =
2p - 6*2p + 6*2 + 2*5p - 2*5 - 3*3p + 3*5

Answer 2

Okay, so would it be 2p-12p+12+10p-10-9p+15

Answer 3

Yep. Then you add the ones with a 'p' in it. And the ones without.
2p-12p+12+10p-10-9p+15 =
(2p-12p+10p-9p)+(12-10+15)

Answer 4

-9p + 17

Answer 5

Oh, I wrote wrong, Im sorry:
2p - 6*2p - 6*2 + 2*5p - 2*5 - 3*3p + 3*5=
2p-12p-12+10p-10-9p+15
(2p-12p+10p-9p)+(-12-10+15)

Answer 6

-9p - 16

Answer 7

Answer 8

-12-10+15 = -22+15 = -7
