Question

Find d(ab) is co-ordinets of a and b are -2 and respectively

Answer 1

if points A,Band C on a coordinate line have coordinates -5,3 and 10 respectively,find d(A,C)+d(B,C).thank you.

DO YOU MEAN A,B,C HAVE SAME X (OR Y ) COORDINATE? IF SO

AB = 3-(-5)=3+5=8

BC = 10-3=7

AC=10+5=15

AC+BC=7+15=22
