Question

if: $$ x=\frac{5}{4} y $$, what is $$ \sqrt{x^{2}-y^{2}} $$ $$ \begin{array}{llll}	ext { 1) } 1 & 	ext { 2)2 } & 	ext { 3) } 3 & 4) 4\end{array} $$

$$ \sqrt{x^{2} - y^{2}} = 3 $$, so the answer is 3.

if: \( x=\frac{5}{4} y \), what is \( \sqrt{x^{2}-y^{2}} \) \( \begin{array}{llll}\text { 1) } 1 & \text { 2)2 } & \text { 3) } 3 & 4) 4\end{array} \)
