Question

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

Explanation:

Step1: Substitute m and n values

Substitute \( m = -7 \) and \( n = 2 \) into \( 3.4|m - n| \).
First, calculate \( m - n \): \( -7 - 2 = -9 \)

Step2: Find the absolute value

Find the absolute value of \( -9 \): \( | -9 | = 9 \)

Step3: Multiply by 3.4

Multiply the absolute value by 3.4: \( 3.4\times9 = 30.6 \)

Answer:

\( 30.6 \)
