anonymous one year ago solve 5 - √20x + 4 > -3? I'll give a gold metal :)

First subtract 4 to both sides, then subtract 5 to both sides. Then you get: $- \sqrt{20x} > -12$ Square both sides of $-\sqrt{20x} > -12$ $-20x > 144$ Divide -20 to both sides x < -7.2 Sign is flipped because when you multiply or divide a negative, you have to switch the sign.

Thank you for the help! That is the answer that I have got, except the only choices are x<3, -1/5<x<3, x>-1/5, or x>0
