Hall and Mindy are playing a guessing game. Hall tells Mindy: ""The difference between 17 and the square root of my mystery numb
cestrela7 [59]

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}

is 5

Then:

17 - \sqrt{x} = 5

What are two possible numbers that Hall could be thinking of?

We have to solve the equation, for x. So

17 - \sqrt{x} = 5

\sqrt{x} = 12

(\sqrt{x})^2 = (12)^2

x = 144

The possible number that Hall could be thinking of is 144.
