Question

The points on x axis which are at a distance of 6 units from the points (-4,2,-1) are.....​

Answer 1

Answer:

Using distance formula for distance between (5,4) and (x, 0)

25 = (5-x)^2 + (4-0)^2

25 = (5-x)^2 + 16

(5-x)^2 = 9

Taking sq. root on both sides,

5-x = 3, 5-x = - 3

x = 2,8
