Question

If 6 is added to the square of a positive number, the sum is 31. Find the number.​

Answer 1

The number is 5.

Explanation:

Given: If 6 is added to the square of a positive number, the sum is 31. Find the number.​

Step-by-step solution:

Step 1: Formula

We know that the square of a positive number plus 6 is equal to 31. In a formula, it would look like
`√(x)` + 6 = 31 where x replaces the positive number.

Step 2: Subtract 6

We need to get x by itself to find the number. Subtract 6 on both sides to cancel it out and move it to the left

so,
`√(x)` + 6 -6 = 31 -6 =
`√(x)` = 25

Step 3: Square Root of 25

The Square Root of 25 is 5. We know this because 5*5 = 25.

Therefore, the number is 5.
