Answer:

x ≤ 17

Step-by-step explanation:

This is the same as solving an equation, except instead of and equal sign it's an arrow.

We have to evaluate everything in the parenthesis first.

3x - 2 (x + 1) ≤ 15

3x - 2x - 2 ≤ 15

Next, we combine like terms - x's

3x - 2x - 2 ≤ 15

x - 2 ≤ 15

Combine like terms - constants (add 2 to both sides)

x - 2 ≤ 15

<u>x ≤ 17</u>

Lets do this step by step.

Simplify: (4x2 - 2x) - (-5x2 - 8x).

~~~~~~~~~~~~~~~~~~~~~~~~~

Solution:

(4x2 - 2x) - (-5x2 - 8x)= 4x2 - 2x + 5x2 + 8x.= 4x2 + 5x2 - 2x + 8x.= 9x2 + 6x.= 3x(3x + 2).

~~~~~~~~~~~~~~~~~~~~~~~~

Answer: 3x(3x + 2)
