Which values are solutions to the inequality below? Check all that apply.

Step-by-step explanation:

Given that

x²>18

So, let take the square root of both sides

Then,

√x²>√18

x> ± 4.24

So it is either

x>4.24 or x<-4.24

Either of the two will gives a square higher than 18. You should note that the square of any number is always positive.

The applicable answer are

A. 5

Because

5²=25 which is greater than 18

D. 8

Because

8²= 64 which is greater than 18

F. -18

Because

(-18)²=-18×-18=324 which is greater than 18.
