Answer:
N=6
Step-by-step explanation:
You need to prime factorize 150. 150 = 3*5*2*5.
x*x=perfect square.
What we have done so far is we have split 150 into a few digits
You can add 5 to one box and 5 to the other.
Next if we add 3 to one box and 2 to the other box, then they wont be equal.
Let's try 5*6 and 5.
6 is missing from the second box, so N must be 6 to create a perfect square.
The perfect square is 900 and 30*30 = 900, so it is a perfect square.

Answer:
AC ≈ 67.9
Step-by-step explanation:
15² = 9 (3x + 1 + 9)
225 = 9 (3x + 10)
225 = 27x + 90
135 = 27x
x ≈ 19.29
AC = (3x + 1 + 9)
AC = 3 (19.2857...) + 1 + 9
AC = 57.857... + 1 + 9
AC = 57.857... + 10
AC ≈ 67.9
