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
= 
( cross- multiply )
x² = 36 ( take the square root of both sides )
x = ± 
= ± 6
Thus x = 6 is the positive value
