## anonymous 4 years ago solve for x... 6/x=x/12 (, six is over x then x is over twelve)

Assuming x is not zero. Multiply both sides by x, then you get 6 = 12x^2 => x^2 = 1/2 => x = +/- 1/sqrt(2).

$\frac{6}{x}=\frac{x}{12}$ $x^2=72$ $\sqrt{x^2}=\sqrt{72}$ $x=\pm \sqrt{72}=\pm \sqrt{36*2}=\pm 6\sqrt{2}$
