can yall help a brother out im in deep sh|t if i dont pass so if your gunna do it do it right thank yall for helpen me out oh and i already tried to look em up so that dont work


if a\geq b then a^{2} \geq b^{2}
if a \neq b then a^{2} \neq b^{2}
\sqrt{x-2} =9
\sqrt{148}
5x^{2} +3=-122
\sqrt{35}
t=\sqrt{\frac{a}{15} }
t=\sqrt{\frac{30}{a} }
t=2\sqrt{\frac{30}{a} }
t=\sqrt{10d}
t=\sqrt{2d}
t=\sqrt{\frac{5d}{2} }
t=\sqrt{\frac{2d}{5} }
-\frac{2}{3}
