What is the scale factor of the dilation shown?

(One side increased from 6 to 8.)

The scale factor of the dilation can be found by comparing the ratio of the corresponding sides before and after the dilation.

Before the dilation: 6
After the dilation: 8

The scale factor is calculated by dividing the length of the corresponding side after the dilation by the length of the corresponding side before the dilation:

8/6 = 4/3

Therefore, the scale factor of the dilation is 4/3.
