Answer 1

Answer:

D is your answer 2x^2 + 4x -30

Step-by-step explanation:

2x^2+10x-6x+30

2x^2+4x+30

If brainiest is earned its greatly Appreciated

Answer 2

Answer:

D) 2x²+4x-30

Step-by-step explanation:

You would multiply x and 2x; x and -6; 5 and 2x; 5 and -6

(x)(2x) = 2x²

(x)(-6) = -6x

(5)(2x) = 10x

(5)(-6) = -30

Now just put it back in the order that it was listed in the equation starting with (x)(2x)

This would give you 2x²-6x+10x-30

Simplify even further to get 2x²+4x-30
