Question

Which values are solutions to the inequality below? Check all that apply.x2 < 81

Answer 1

A(6) and D(-4) are solutions to the equations

(6)^2 < 81  |  36 < 81

(-4)^2 < 81  |  16 < 81

Answer 2

I just did one like this with you.
Take the number and square it. If it is less than 81, it is a solution. It cannot = 81 because the inequality is only <.
