HELP ASAP Simplify the following expression:
2x − 8y + 3x2 + 7y − 12x

Question options:

3x2 − 14x − y

3x2 − 10x − y

3x2 − 10x − 15y

3x2 + 10x − y

2x-8y+3x^2+7y-12x

COMBINE LIKE TERMS

3x²+(2x-12x)+(-8y+7y)

ADD LIKE TERMS

3x^2-10x-y

Therefore the answer is the 2nd option: 3x^2-10x-y

So its B

Step-by-step explanation:

Combine like terms

2 −  8 + 3 2 + 7 −  1 2

2  −    +  3  2  −  1 2

2  −    +  3 2  −  1 2

− 1 0  −    +  3  2

Rearrange terms

− 1 0  −    +  3 2

3 2  −  1 0  −  

Solution

3x2 − 10x − y

.632

step-by-step explanation:

6 * 1/10 = 3/5

3*0.01 = 0.03

3/5 + 0.03 = .63

2*0.002 = .002

.63 + 0.002 = .632

x = 17

step-by-step explanation:

1st step: isolate x.

24 - 3x = -27

-24         -24

-3x   =   -51

2nd step: divide.

-3x     =   -51

  3             3

  x       =     17

hope this
