Question 627883: What is the distance between the points (21, -30) and (3, 8)?
Answer by jim_thompson5910(35256) (Show Source): You can put this solution on YOUR website!
d = sqrt((x2-x1)^2+(y2-y1)^2)

d = sqrt((3-21)^2+( 8-( -30))^2)

d = sqrt((3-21)^2+( 8-( -30))^2)

d = sqrt((-18)^2+(38)^2)

d = sqrt(324+1444)

d = sqrt(1768)

d = 2*sqrt(442)

So exact distance between the two points is 2*sqrt(442) units.
