The scale factor is 3. Why? Well, B and D can already be ruled out because when dilating a figure, an enlargement is displayed by a scale factor greater than one, not less than one. From here, each side length can simply be multiplied by three to get the enlargement size, and you will see that it aligns. AB (which is 5) x 3 = DE (which is 15). AC (which is 3) x 3 = DF (which is 9). BC (which is 4) x 3 = EF (which is 12).
Your final answer: C. If you need to better understand it, let me know and I will gladly assist you!
The variation(both the skein values and cost values) has the constant of 4 ie the 1st skein value × 4= the last skein value & the 1st cost value × 4=the last cost value
