Answer 1

Hi
This is really easy you just have to add and subtract 3 from 3
12+3=15
12-3=9
But I notice on the answers their is -15 and -9 so if your doing absolute value you do it like this |-12|=12 so also -9 and -15.
Let me know if this helps!

Answer 2

15 and 9 are the correct answers.

Explanation:

The numbers that are at a distance of 3 units from 12 on a number line are given as:

We will add 3 to 12 and also subtract 3 from 12 to get both numbers on the left side an right side on the number line.

`12+3 = 15`

`12-3 = 9`

So, the correct answers are 15 and 9.
