The total cost on the bracelet would be $225.75
8x+6-9x= 2-x+4
8x+6+-9x=2+-x+4
(8x + -9x) + (6) = (-x) + (2+4) (combine like terms)
-x+6= -x+6
-x+6+x=-x+6+x
6-6=6-6
0=0

You can think of a square as two isosceles right angle triangles and use Pythagoras.
x^2 + x^2 = 22^2
x^2 + x^2 = 484
2x^2 = 484
x^2 = 242
x = 11√2
One side of the playground is 11√2 m long.
