Geometry

The answer is A. .

 

1. First, recall the formula for the length of a line - segment on a number line:

If two points and have coordinates and on a number line, the length of the line - segment is given by .

 

2. Calculate the lengths of each line - segment:

For : The coordinate of and the coordinate of . Then .

For : The coordinate of and the coordinate of . Then . So, since .

 

For : The coordinate of and the coordinate of . Then .

For : The coordinate of and the coordinate of . Then . Since and
