Answer:
121
Step-by-step explanation:
you can either set up a proportion or a table (i inserted a picture for both ways!) After setting up a table you would calculate how much it is to get from 2.5 to 27.5 (so you divide 27.5/2.5) to get 11. Then you move to the y side of the table where you would have to multiply 11×11 to get your answer (which is 121)

The given equation of n is and we have to solve it for n.
........... (1)
⇒
{Rationalizing the numerator}
⇒ .............. (2)
Now, adding (1) and (2) we get
⇒ n + 5 = 64 {Squaring both sides}
⇒ n = 59 (Answer)
