the answer to your problem is 6. hopefully this helped. all i did was divide 30 by 5 to get 6 and 24 divided by 4 to get 6 as well
To find a scale factor divide corresponding parts from the preimage to the image.

This would be 30/5. 
- 30 is the length of the preimage
- 5 is the length of the image


This would result in 6.


So the scale factor is 6.


Hope this helps. If you have any questions, place it in the comment section below.
