The answer is B basketball to dance
For this case, the first thing to do is find the scale factor.
We have then:
![k = \frac{A'B'}{AB}](https://tex.z-dn.net/?f=k%20%3D%20%20%5Cfrac%7BA%27B%27%7D%7BAB%7D%20)
Substituting values we have:
![k = \frac{24}{4}](https://tex.z-dn.net/?f=k%20%3D%20%5Cfrac%7B24%7D%7B4%7D%20)
Rewriting:
![k = 6](https://tex.z-dn.net/?f=k%20%3D%206)
Then, we apply the scale factor to find the length of B'C '.
We have then:
![B'C '= k * BC ](https://tex.z-dn.net/?f=B%27C%20%27%3D%20k%20%2A%20BC%0A)
Substituting values:
Answer:
the length of segment B'C 'is:
B'C '= 18 in
