The simplified solution to this equation is 5x - 115.
Answer: 11
Students have both a brother and a sister
Step-by-step explanation:
I don't think probability should be used for this question because the answer is quite clear
So in a class of 25 students
5 students don't have a sibling
So 25-5=20
Total number of siblings=14+17=31 siblings in total
So 20 people have 31 siblings
31-20=11
So the answer should be 11

<h3>Given expression is ,</h3>
![\large{lim_{x→5} \: \frac{ {x}^{2} - 5 }{ {x}^{2} + x - 30} }](https://tex.z-dn.net/?f=%20%5Clarge%7Blim_%7Bx%E2%86%925%7D%20%5C%3A%20%5Cfrac%7B%20%7Bx%7D%5E%7B2%7D%20-%205%20%7D%7B%20%7Bx%7D%5E%7B2%7D%20%2B%20x%20-%2030%7D%20%7D)
if we substitute directly x=5, we get
![\longrightarrow \: \frac{ {5}^{2} - 5}{ {5}^{2} + 5 - 30 }](https://tex.z-dn.net/?f=%20%5Clongrightarrow%20%5C%3A%20%20%5Cfrac%7B%20%7B5%7D%5E%7B2%7D%20%20-%205%7D%7B%20%7B5%7D%5E%7B2%7D%20%2B%205%20-%2030%20%7D%20)
![\longrightarrow \: \frac{25 - 5}{30 - 30}](https://tex.z-dn.net/?f=%5Clongrightarrow%20%5C%3A%20%20%5Cfrac%7B25%20-%205%7D%7B30%20-%2030%7D%20)
![\longrightarrow \: \frac{20}{0}](https://tex.z-dn.net/?f=%5Clongrightarrow%20%5C%3A%20%20%5Cfrac%7B20%7D%7B0%7D%20)
![\longrightarrow \: \infty](https://tex.z-dn.net/?f=%5Clongrightarrow%20%5C%3A%20%20%5Cinfty%20)
Hence,
![{\red{ \boxed{\large{lim_{x→5} \: \frac{ {x}^{2} - 5 }{ {x}^{2} + x - 30 } = \infty}}}}](https://tex.z-dn.net/?f=%20%7B%5Cred%7B%20%5Cboxed%7B%5Clarge%7Blim_%7Bx%E2%86%925%7D%20%5C%3A%20%5Cfrac%7B%20%7Bx%7D%5E%7B2%7D%20-%205%20%7D%7B%20%7Bx%7D%5E%7B2%7D%20%2B%20x%20-%2030%20%7D%20%20%3D%20%20%5Cinfty%7D%7D%7D%7D)
