Answer:
B
Step-by-step explanation:
Answer:
![(r-24)](https://tex.z-dn.net/?f=%28r-24%29)
Step-by-step explanation:
![X=r+2](https://tex.z-dn.net/?f=X%3Dr%2B2)
![Y=2r-9](https://tex.z-dn.net/?f=Y%3D2r-9)
![Z=r^2+17r+30](https://tex.z-dn.net/?f=Z%3Dr%5E2%2B17r%2B30)
Let us find
X.Y-Z
![(r+2)(2r-9)-(r^2+17r+30)](https://tex.z-dn.net/?f=%28r%2B2%29%282r-9%29-%28r%5E2%2B17r%2B30%29)
![(2r^2-9r+4r-18)-(r^2+17r+30)](https://tex.z-dn.net/?f=%282r%5E2-9r%2B4r-18%29-%28r%5E2%2B17r%2B30%29)
![2r^2-r^2-5r-17r-18-30](https://tex.z-dn.net/?f=2r%5E2-r%5E2-5r-17r-18-30)
![r^2-22r-48](https://tex.z-dn.net/?f=r%5E2-22r-48)
![r^2-24r+2r-48](https://tex.z-dn.net/?f=r%5E2-24r%2B2r-48)
![r(r-24)+2(r-24)](https://tex.z-dn.net/?f=r%28r-24%29%2B2%28r-24%29)
![(r-24)(r+2)](https://tex.z-dn.net/?f=%28r-24%29%28r%2B2%29)
Now we divide it by X i.e. (r+2)
[X.Y-Z]÷X
![\frac{(r-24)(r+2)}{(r+2)}](https://tex.z-dn.net/?f=%5Cfrac%7B%28r-24%29%28r%2B2%29%7D%7B%28r%2B2%29%7D)
![=(r-24)](https://tex.z-dn.net/?f=%3D%28r-24%29)
