Question

Hall and Mindy are playing a guessing game. Hall tells Mindy: ""The difference between 17 and the square root of my mystery number is 5"". What are two possible numbers that Hall could be thinking of?

Answer 1

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

Explanation:

Difference between 17 and the square root of my mystery number

This is represented by:

`17 - √(x)`

is 5

Then:

`17 - √(x) = 5`

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

We have to solve the equation, for x. So

`17 - √(x) = 5`

`√(x) = 12`

`(√(x))^2 = (12)^2`

`x = 144`

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