Can someone please check my work?
Applying the Pythagoras theorem c^2 = a^2 + b^2
c = (10x + 15y)
a = (6x + 9y)
b = (8x + 12y)
a
(10x + 15y)^2 = (6x + 9y)^2 + (8x + 12y)^2
Second, transform each side of the equation to determine if it is an identity.
b
100x^2 + 150xy + 225y^2 = 36x^2 + 54xy + 81y^2 + 64x^2
100x^2 + 150xy + 225^2 = 100x^2 + 150xy + 225^2
The left side is equal to the right side, therefore they are an identity.
