Use this formula:
{a}^{2}  +  {b}^{2}  =  {c}^{2}
you know A and B
a=12 ft and b=12ft, so:
{12}^{2}  +  {12}^{2}  =  {c}^{2}
144 + 144  = 288
{c}^{2}  = 288
c =  \sqrt{288}  = rounded \: 17ft

x^2 + (3y/2z) = 7
2x^2z + 3y = 14z
3y = 14z - 2x^2z
3y = 2z(7 - x^2)
  y = 2/3(z)(7 - x^2)

2)
(3zx^4) /(5+z) = 2y
3zx^4 = 2y(5+z)
3zx^4 = 10y + 2yz
