What methods could you use to calculate the x-coordinate of the midpoint of a horizontal segment with the endpoints of (-20, 0) and (20, 0)?
a. divide 2 by 20
b. take the average of the endpoints
c. divide 0 by 20
d. calculate the average of the x-coordinates
e. divide 20 by 2

option B and D

Step-by-step explanation:

we need to calculate the x-coordinate of the midpoint of horizontal line segment

To find midpoint of x coordinate , add the x coordinate of the given points and divide by 2

(-20, 0) and (20, 0)

The x coordinates of end points are -20 and 20

HEre we divide 0 by 2 not 0 by 20

WE take the average of the endpoints

or calculate the average of the x coordinates
