It's the third one because if you look at the other ones
Answer:
He switched the divisor and the dividend when creating an equation to model the problem in step 1.
Step-by-step explanation:
got it right on edgenity quiz
Multiply first equation by -5 and 2nd by 2, add them
15x+20y=-100
<u>2x-20y=32 +</u>
17x+0y=-68
17x=-68
divide both sides by 17
x=-4
the x value is -4
Simplify the expression 5(x-3)(x^2+4x+1)
it would be I think answer number 3
