Please only answer this if you know the answer. If you have a comment, please add it to the comment box. Only answer the question if you can explain your answer and why you think it is accurate. Thanks, good luck!

What is the scale factor of the dilation shown? Leave your answer as a fraction please.

Answer 1

The scale factor is 3/2.

Explanation:

Let's use the side PQ.

The original length was 8 units.

And the new length is 12 units.

Let the scale factor be k. Therefore:

`8k=12`

By dividing both sides by 8, we can see that our scale factor from ΔPQR to ΔP'Q'R' is:

`\displaystyle k=(12)/(8)=(3)/(2)`
