Factor completely 5ax2 − 20x3 + 2a − 8x.

(a-4x)(5x^2+2)

Step-by-step explanation:

5ax^2 − 20x^3 + 2a − 8x.

We will factor by grouping.

Take 5x^2 out of the first 2 terms and 2 out of the last 2 terms

5x^2(a-4x) + 2(a − 4x)

Now we can factor a (a-4x) out

(a-4x)(5x^2+2)

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180

step-by-step explanation:

1. x> -5

2. x< 8

step-by-step explanation:

1. 2x> -10

divide by 2 from both sides of equation.

2x/2> -10/2

simplify, to find the answer.

-10/2=-5

x> -5 is the correct answer.

2. 3x< 24

divide by 3 from both sides of equation.

3x/3< 24/3

simplify, to find the answer.

24/3=8

x< 8 is the correct answer.

i hope this you, and have a wonderful day!
