Find the length of AB, A=13, B=34. AB=(a-b)=(b-a)

Answer 1

To find the length \( AB \) where \( A = 13 \) and \( B = 34 \), we use the formula for the distance between two points on a number line:

\[ AB = |A - B| \]

This can be calculated as:

\[ AB = |13 - 34| = |-21| = 21 \]

Thus, the length of \( AB \) is \( 21 \).
