Answer: The scale factor is 1.3 .
Step-by-step explanation:
Given: The first hexagon is dilated to form the second hexagon.
The side length of first hexagon=5 units.
The side-length of second hexagon= 6.25 units
When a shape having measure x is dilated by using a scalar factor of k, then the side measure (y) of the image is given by:-
[tex]y=kx[/tex]
Substitute, y=6.5 and x=5 to find the value of k we get
[tex]6.5=5k\\\Rightarrow\ k=\frac{6.5}{5}=1.3[/tex]
Hence, the scale factor is 1.3
