Find the expression that represents the length of the hypotenuse of a right triangle whose legs measure 2x^2 - y^2 and 2xy. ​

By pythagorean theorem,

First simplify RHS,

Take square root of both sides,

So the answer is A.

Hope this helps :)

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3

sorry not sure
