b) $|- 28|$
c) $[0]$

Short Answer

Expert verified

Part(a) The required answer is $4$

Part(b) The required answer is $28$

Part(c) The required answer is $0$

Step by step solution

Part(a) Step 1. Given Information

We have, $|4|$

Part(a) Step 2. Calculation

The absolute value of a number is the distance between the number and zero. The absolute value will not be negative as distance is never negative.

So, $|4| = 4$

Part(b) Step 1. Given Information

We have, $|- 28|$

Part(b) Step 2. Calculation

The absolute value of a number is the distance between the number and zero. The absolute value will not be negative as distance is never negative.

$|- 28| = 28$

Part(c) Step 3. Given Information

We have, $|0|$

Part(c) Step 2. Calculation

The absolute value of a number is the distance between the number and zero. The absolute value will not be negative as distance is never negative.

So, $|0| = 0$
