Question

4|m - n| if m = -7 and n = 2

Explanation:

Step1: Substitute m and n values

Substitute \( m = -7 \) and \( n = 2 \) into \( |m - n| \).
\( |-7 - 2| \)

Step2: Calculate inside the absolute value

Simplify the expression inside the absolute value.
\( |-9| \)

Step3: Find the absolute value

The absolute value of -9 is 9. Then multiply by 4.
