Answer:

Answer ::+-6

Step-by-step explanation:

x:3=12:x

or, x/3 = 12/x

Doing cross multiplication,

x^2=36

Putting sqare root on both sides,

x= sqrt. 36

x= +- 6

Therefore x=+-6.

Answer:

x = 6

Step-by-step explanation:

Express the ratio in fractional form, that is

\frac{x}{3} = \frac{12}{x} ( cross- multiply )

x² = 36 ( take the square root of both sides )

x = ± \sqrt{36} = ± 6

Thus x = 6 is the positive value
