X² + 4x + 4 = 25
(x+2)² = 25
x + 2 = <span>±5
x + 2 = -5 or x + 2 = 5
x = -5 -2 x = 5 - 2
x = -7 x = 3
</span><span>The solutions are x=-7 and x=3</span>

Step-by-step explanation:
<u>Step 1: Define Inequality</u>
15 < -5x
<u>Step 2: Solve for </u><em><u>x</u></em>
- Divide -5 on both sides: -3 > x
- Rewrite: x < -3
Here we see that any number <em>x</em> that is smaller than -3 would work as a solution to the inequality.

Check the picture below.
notice that the triangle ADH, since the segment AL is an angle bisector, meaning it cuts the angle A in two equal halves, then the triangle ADH is only using half of A.
