Explanation:

Step1: Simplify the expression inside the absolute value

We have \(|28 - (-20)|\). Subtracting a negative is like adding the positive, so \(28 - (-20)=28 + 20\).
\(28+20 = 48\)

Step2: Evaluate the absolute value

The absolute value of 48 is 48, since the absolute value of a positive number is the number itself.
