Question

1. what is the value of 8.4n - 3.2p when n = 2 and p = 4?

Explanation:

Step1: Substitute n and p values

Substitute \( n = 2 \) and \( p = 4 \) into \( 8.4n - 3.2p \).
\( 8.4\times2 - 3.2\times4 \)

Step2: Calculate each term

Calculate \( 8.4\times2 = 16.8 \) and \( 3.2\times4 = 12.8 \).
