Question

coordinates of point of pairs are X+3andX-3,then distance between them
​

Answer 1

Hi ,

Representing given points on the number line,

<-----•(x-3)--------------•(x+3)------>

Distance between two points

D = x + 3 - ( x - 3 )

= x + 3 - x + 3

= 6

Therefore ,

Required distance ( D ) = 6
