assume that the wooden triangle shown is a right triangle.

a. write an equation using the pythagorean theorem and the measurements provided in the diagram.
hint: (leg 1)^2 + (leg 2)^2 = (hypotenuse)^2

b. transform each side of the equation to determine if it is an identity.

Here's what I get  

Step-by-step explanation:

a. Write an equation

(8x + 12y)² + (6x + 9y)²= (10x + 15y)²

b. Transform the equation

(i) Remove parentheses

64x² +192xy + 144y² + 36x² + 108xy + 81 y² = 100x² +300xy + 225y²

(ii) Combine like terms.

100 x² + 300xy + 225y² = 100x² +300xy + 225y²

The two sides are the same.

The equation is an identity.

1/5x+9 2/5y+7

step-by-step explanation:

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.
