Eli had $10, but he lost some of it. His mom doubled the money he had left. Eli wrote the expression 2(10 – k) to show how much money he has now, where k is the amount
of money he lost. Aisha wrote another correct expression, 20 - 2k, to also show how
much money Eli has now.

because that’s us why

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.

combine all like terms then its just a 2 step equation
