Help! It says what is the scale factor but there are no number! or anything!!!!

DFN's sides are twice as big as GHM's, therefore, the scale factor is 2. You just need to type in a 2 in the box
Answer:
2
Step-by-step explanation:
The corresponding sides between triangles DFN and GHM are twice as big, so the scale factor is 2.
For example, if it was the scale factor from triangle DFN *to* GHM the scale factor would be 1/2 since GHM is half the size of DFN.
i hope this makes sense!! <3
