Question

Given A = ( x+2, -1) and B( 11,7) and the distance of AB is 17 find the value x

Answer 1

Answer:

24

Step-by-step explanation:

distance between two points is sq. root of (x1-x2)sq + I (y1-y2)sq...if you apply this formula, you will get (x-24)(x+6) = 0, equating this you get 24 OR -6 ,if you apply -6, you won't get distance of 17, so applying 24, you will get sq. root of 225+64=289. which is 17
