Question

1. 4|m - n| if m = -7 and n = 2

Explanation:

Step1: Substitute m and n values

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

Step2: Find the absolute value

Find the absolute value of \( -9 \), which is \( | -9 | = 9 \).

Step3: Multiply by 3.4

Multiply \( 3.4 \) by \( 9 \): \( 3.4 \times 9 = 30.6 \).

Answer:

\( 30.6 \)
