Question

Which values are solutions ? check all that apply

Answer 1

A
C
F

*100 would be less than or equal to, not just less than, so it wouldn't be a solution.

Answer 2

Square both sides of the inequality to find
  x < 100
We also know that the square root is only defined for x ≥ 0, so selection A will not be a solution.

C and F are values less than 100.
