![((3)/(5))](https://img.qammunity.org/2021/formulas/history/middle-school/y24tgzyyfmqa6le626f0nzluer968pq2sw.png)
Step-by-step explanation:
This question is mathematics not history; however, the solution is as follows.
Given
Line Segments A'B' and AB
Center of Dilation = P
![A'P = 3](https://img.qammunity.org/2021/formulas/history/middle-school/u2e1ano13nxaf57bi31klv6jm6p2lt5w55.png)
![AP = 5](https://img.qammunity.org/2021/formulas/history/middle-school/7wlz8xm8lw38lkocm7ct17zxf43gvo6oq8.png)
Required
Scale factor of dilation;
The scale factor of dilation is defined as thus;
Scale Factor is the ration of the distance between the center points and origin of the dilated line segment to the original line segment;
In other words;
![Scale Factor = (A'P)/(AP)](https://img.qammunity.org/2021/formulas/history/middle-school/mwhpef65z5ox407ls2n820ymxtd8hxzj8o.png)
Substitute
and
![AP = 5](https://img.qammunity.org/2021/formulas/history/middle-school/7wlz8xm8lw38lkocm7ct17zxf43gvo6oq8.png)
![Scale Factor = (3)/(5)](https://img.qammunity.org/2021/formulas/history/middle-school/q2wzu9dyignwwvee3e9k3n6snkv38b3pvr.png)
Hence, the scale factor of this dilation is Three-fifths or
![((3)/(5))](https://img.qammunity.org/2021/formulas/history/middle-school/y24tgzyyfmqa6le626f0nzluer968pq2sw.png)
