h =121
You did do good rarinstraw1195 BUT
h could also equal -11
\(h^2=121\\ h=\pm\sqrt{121}\\ h=\pm \;11\)
To figure out what h is, you would do the opposite of squaring. The opposite of squaring is square rooting, so you would square root both sides, giving you h=11.
Did I do good mods?
Right! Totally forgot! Thanks Melody!
