PLS HELP ME ASAP
FOR THE THIRD PICTURE, I JUST NEED THAT ANSWER FOR THE SECOND ONE

Answer 1

3. If ∞ < - 18, then x - (-18) = × + 18.
Therefore, we can simplify the expression as:

| x- (-18) | as:

| x-(-18) | = | x+18 | = -(x+18)

The negative sign comes from the fact that
x + 18 is negative when x < - 18.

So the simplified expression is:
| x- (-18) | = -(x+18) if x < -18
