2(5x + 2)^2 = 48
divide both sides by 2
(5x + 2)^2 = 24
square root both sides to clear the power of two.
5x + 2 = + - sqrt24
subtract 2 from both sides
5x = -2 + - sqrt 24
divide both sides by 5
x = (-2 +-sqrt24)/5 or decimal answers .58 and -1.38

Step-by-step explanation:

<u>Step 1: Define</u>

-25x + 14 > 20

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Subtract 14 on both sides:                    -25x > 6
  2. Divide -25 on both sides:                     x < -6/25

Here we see that any number <em>x</em> less than -6/25 would work as a solution to the inequality.
