Answer:
The possible number that Hall could be thinking of is 144.
Step-by-step explanation:
Difference between 17 and the square root of my mystery number
This is represented by:
![17 - \sqrt{x}](https://tex.z-dn.net/?f=17%20-%20%5Csqrt%7Bx%7D)
is 5
Then:
![17 - \sqrt{x} = 5](https://tex.z-dn.net/?f=17%20-%20%5Csqrt%7Bx%7D%20%3D%205)
What are two possible numbers that Hall could be thinking of?
We have to solve the equation, for x. So
![17 - \sqrt{x} = 5](https://tex.z-dn.net/?f=17%20-%20%5Csqrt%7Bx%7D%20%3D%205)
![\sqrt{x} = 12](https://tex.z-dn.net/?f=%5Csqrt%7Bx%7D%20%3D%2012)
![(\sqrt{x})^2 = (12)^2](https://tex.z-dn.net/?f=%28%5Csqrt%7Bx%7D%29%5E2%20%3D%20%2812%29%5E2)
![x = 144](https://tex.z-dn.net/?f=x%20%3D%20144)
The possible number that Hall could be thinking of is 144.
