Suppose z varies directly as the square of x and inversely as y. If z = 8 when x = 4 and y = 6, find z when x =6 and y = 12.
You must have meant z instead of x, so I changed the first x to a z.
means z varies directly with the square of x and inversely as y.
Substitute and solve for k.

Your new formula is:
Substitute and solve for z.

Happy Calculating!!!
