For what values of x is x^2-36=5x true?

-9 and -4
-4 and 9
4 and -9
9 and 4

The answer is 9 and -4

You will use the quadratic formula to arrive at the answer.

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.
