Question

what is the distance between -29 and -8? units

Explanation:

Step1: Recall distance formula on number line

The distance between two numbers \( a \) and \( b \) on the number line is \( |a - b| \). Here, \( a=-29 \) and \( b = -8 \).

Step2: Substitute values into formula

Calculate \( |-29 - (-8)| = |-29 + 8| = |-21| \).

Step3: Evaluate absolute value

The absolute value of \( -21 \) is \( 21 \), so \( |-21| = 21 \).

Answer:

21
