Question

What is the scale factor of AUVWto AXYZ?

Answer 1

Step-by-step explanation:

Scale Factor of UVW to XYZ

= XY/UV = YZ/VW = XZ/UW

= 21/3 = 28/4 = 14/2

= 7. (B)

Answer 2

7, because UV(3)-XY(21), VW(4)-YZ(28), and WU(2)-ZX(14). To get from the first number in each set to the second number, multiply by 7. :)
