Question

what is the length of \\(\overline{fg}\\)?

Explanation:

Step1: Identify coordinates of F and G

From the number line, \( F \) is at \( -20 \) and \( G \) is at \( 20 \).

Step2: Calculate the distance between F and G

The distance between two points \( x_1 \) and \( x_2 \) on a number line is \( |x_2 - x_1| \). So, \( |20 - (-20)| = |20 + 20| = |40| = 40 \).

Answer:

40
