What is the scale factor of triangle abc to triangle uvw where abc has side lengths 5,4,3, and uvw has side lengths 25,20,15

Because the ABC sides lengths are 5,4,3 and checked these sides length 25,20,15 so we get that 5*5=25,4*5=20 and 3*5=15

so from this result that the scale factor is 1:5 

hope this will help you 

The answer to your question is b’(16,14)
