sarah had 28 stickers and put x number of stickers on her binded. haylee had 40 stickers and put three times as many stickers on
Mariana [72]

Answer:

Number of stickers Sarah had = 28

Number of stickers she put on her binder = x.

Number of stickers left with her = 28 - x

Number of stickers Haylee had = 40

Number of stickers she put on her locker = 3x

Number of stickers left with her = 40 - 3x

Both Sarah and Haylee had the same number of stickers left.

28 - x = 40 - 3x

=> 3x - x = 40 - 28

=> 2x = 12

=> x =  = 6

Please help me for my finals!! I'll do anything
oee [108]

Choice (B) is not the right answer because I

it's only 3rd order. But because f(x) goes to negative infinity when x goes to positive infinity means that the right answer is (A).

vfiekz [6]

((3x^2)^a - (4y^a)(z^3a))^2

First, expand.

((3x^2)^a - (4y^a)(z^3a)) ((3x^2)^a - (4y^a)(z^3a))

Combine

3^(2a) - x^(4a) - 8 * 3^(2a)x^(2a)y^(a)z^(3a) + 16y^(3a)z^(6a)

hope this helps
