Answer: 20+35=55+20=75
![x^{2} x^{2} x^{2} x^{2} x^{2} x^{2} x^{2} x^{2} x^{2} x^{2}](https://tex.z-dn.net/?f=x%5E%7B2%7D%20x%5E%7B2%7D%20x%5E%7B2%7D%20x%5E%7B2%7D%20x%5E%7B2%7D%20x%5E%7B2%7D%20x%5E%7B2%7D%20x%5E%7B2%7D%20x%5E%7B2%7D%20x%5E%7B2%7D)
Step-by-step explanation:

Answer:
![x = 14.31](https://tex.z-dn.net/?f=x%20%3D%2014.31)
Step-by-step explanation:
According to PYTHAGORAS Theorem,
let the Hypotenuse be x
![{6}^{2} + {13}^{2} = {x}^{2} \\ 36 + 169 = {x}^{2} \\ 205 = {x}^{2} \\ \sqrt{205} = x \\ x = 14.31](https://tex.z-dn.net/?f=%20%7B6%7D%5E%7B2%7D%20%20%2B%20%20%7B13%7D%5E%7B2%7D%20%20%3D%20%20%7Bx%7D%5E%7B2%7D%20%20%5C%5C%2036%20%2B%20169%20%3D%20%20%7Bx%7D%5E%7B2%7D%20%20%5C%5C%20205%20%3D%20%20%20%7Bx%7D%5E%7B2%7D%20%20%20%5C%5C%20%20%5Csqrt%7B205%7D%20%20%3D%20x%20%5C%5C%20x%20%3D%2014.31)
N^2 - n = 90
n^2 - n - 90 = 0
(n - 10)(n + 9) = 0
n - 10 = 0
n = 10
n + 9 = 0
n = -9
answer is : n = 10 and n = -9
4-2(6) I believe that the solution to this problem is C) -8. I hope this helps!!!!
