                A garden has the shape of a right triangle with one leg 
8
meters longer than the other. The hypotenuse is
8
meters less than twice the length of the shorter leg. What is the length of the shorter leg?

    short leg = x
long leg = x+8
hypotenuse = 2x-8
so
{ 2(x-4) }^2 = x^2 + (x+8)^2
4 (x^2 - 8 x + 16)= x^2+x^2+16x+64
4x^2 -32 x + 64 = 2 x^2 +16 x + 64
2 x^2 -48 x = 0
x = 0 works
but
x = 24
*******************
check
24 , 32 , 40
or /8
3 , 4, 5 LOL yes, right triangle
