Answer:

6

Explanation:

You want the x-coordinate of the midpoint of segment AB with endpoint coordinates A(21, 5) and B(-9, -13).

The midpoint of a line segment has coordinates that are the average of the endpoint coordinates:

M = (A +B)/2

M = ((21, 5) +(-9, -13))/2 = (12, -8)/2

M = (6, -4)

The midpoint of AB is (6, -4).

The x-coordinate of the midpoint is 6.
