Question 765490


A scale factor is the {{{ratio}}} of any two corresponding lengths in two similar geometric figures. 
Note: 
The ratio of areas of two similar figures is the square of the scale factor. 
The ratio of volumes of two similar figures is the cube of the scale factor.

A scale factor is also a number which scales, or multiplies, some quantity. In the equation {{{y = ax}}}, {{{a}}} is the scale factor for {{{x}}}. {{{a}}} is also the coefficient of {{{x}}}.
