Question

3(2y - 8) - 2y(5 - y)

-2y2+ 16y - 24
-5y - 8
2y2- 4y - 24
2y2+ 16y - 24

Answer 1

help sos]

Answer 2

Just use the distributive property over and over until no parentheses remain, then collect like terms to simplify.
\[3(2y-8)-2y(5-y) = 3*2y-3*8-2y(5-y) = 6y-24-2y(5-y)\]I'll let you do the rest. Don't forget that if you have negative number on the outside of the parentheses, it gets applied to each term within...

Answer 3

what!!!!

Answer 4

distributive property:

\[a(b+c) = ab + ac\]

Answer 5

ur not getting the medal ur not helping

its hard

Answer 11

I think he doesn't understand how you have written it. @whpalmer4 maybe write in verticle.

Answer 12

plz

Answer 13

Do you understand the distributive property of multiplication?

\[a(b+c) = a*b + a*c\]Think of it with numbers:
10*16 = 160
10*(4+12) = 160
10*4 + 10*12 = 40 + 120 = 160

Answer 14

For the first part of your equation, you have
\[3(2y - 8)\]We multiply 3 and 2y, which gives 6y. We multiply 3 and -8, which gives -24. We add them together, and get \(6y-24\) so
\[3(2y-8) = 6y-24\]
Yes?

Answer 15

umm

Answer 16

screw it im guessing

Answer 17

If you don't understand this, math classes are going to be a torment...good luck!

Answer 18

...

Answer 19

3(2y - 8) - 2y(5 - y)
= 6y - 24 - 10y + 2y^2
Understand?

Answer 20

Put y^2 values together y values together and -24 seperate..
