Hey!
RS = 15 and RT = 18. Subtract 18 from 15 to get your answer.
![18 - 15 = 3](https://tex.z-dn.net/?f=%2018%20-%2015%20%3D%203%20)
<em>That means your answer is 3</em>

Answer:
A) ![f^{-1}(n)= (n+2)^3](https://tex.z-dn.net/?f=f%5E%7B-1%7D%28n%29%3D%20%28n%2B2%29%5E3)
Step-by-step explanation:
![f(n) = \sqrt[3]{n} -2](https://tex.z-dn.net/?f=f%28n%29%20%3D%20%5Csqrt%5B3%5D%7Bn%7D%20-2)
![y = \sqrt[3]{n} -2](https://tex.z-dn.net/?f=y%20%3D%20%5Csqrt%5B3%5D%7Bn%7D%20-2)
![y = n^{1/3}-2](https://tex.z-dn.net/?f=y%20%3D%20n%5E%7B1%2F3%7D-2)
![n = y^{1/3} -2](https://tex.z-dn.net/?f=n%20%3D%20y%5E%7B1%2F3%7D%20-2)
![n + 2 = y^{1/3}](https://tex.z-dn.net/?f=n%20%2B%202%20%3D%20y%5E%7B1%2F3%7D)
![y = (n + 2) ^3](https://tex.z-dn.net/?f=y%20%3D%20%28n%20%2B%202%29%20%5E3)
![f^{-1}(n) = (n + 2)^3](https://tex.z-dn.net/?f=f%5E%7B-1%7D%28n%29%20%3D%20%28n%20%2B%202%29%5E3)
Hope this helps!
