Question

Find the distance between the points a (a,

b.and b (b,

a.if a – b = 4.

Answer 1

sorry but I can't understand Ur question so that's why I am not answered u

Answer 2

put b=(a-4) in given points
A(a,a-4) and B(a-4,a).
by distance formula
AB=
$\sqrt{(a - 4 - a) {}^{2} + (a - (a - 4) {})^{2} }$
=√32
