2x3 + 6x2 + 10x + 30. 2(x3 + 3x2 + 5x + 15) 2[(x2 + 5)(x + 3)] (2x2 + 10)(x + 3) (x2 + 5)(2x + 6)

2[(x^2 + 5)(x + 3)]

Explanation:

Use factoring by grouping to solve this.

(Just took test)

answer: 100

step-by-step explanation:

hey there! : )

4y < -4

we need to isolate y. we can do this by simply dividing both sides by 4.

4y ÷ 4 > -4 ÷ 4

simplify.

y > -1

5 - y > 0

once again, we need to isolate y, so we can start off by subtracting 5 from both sides.

5 - y - 5 > 0 - 5

simplify.

-y > -5

divide both sides by -1.

** remember that when dividing any side by a negative, you must switch the sign! **

-y ÷ -1 < -5 ÷ -1

simplify.

y < 5
