Answer 14

nevermind!! sorry (:

Answer 15

:)

Answer 16

simplify
3x + 4y -7y + x - 10x

Answer 17

-3y-9x+3x
-3y-6x
-3(y+2x)

Answer 18

simplify
-14z^3 + 11z - 8z^2 -9z^3 =7z^2 =5z

Answer 19

and all the = is suposed to be a +

Answer 20

sorry

Answer 21

kk 1 sec

Answer 22

-14z^3-9z^3-8z^2+7z^2+11z+5z
-23z^3-z^2+16z
z(-23z^2-z+16)
