Question

3. If the distance between the points (m. 2m ) and (4m, 4m) is √13, find the value of m.​

Answer 1

let the points be P (m,2m) and Q(4m,4m)

Explanation:

The distance between the point PQ is given by :

(PQ)^2 =(4m-m)^2+(4m-2m)^2

or ,(√13)^2 = 9m^2 +4m^2

therefore x = 1 ( solve the equation)
