PLEASE HELP!!!!!!!!!!!!!!!!!!!!!!!!! MEDAL AWARDED

Find the length of a segment that has endpoints H(2, -3) and J(12, 7). (1 point)

A. 20
B. 10√2
C. 4√2
D. 40

Answer 1

use the distance formula which is:
\[\sqrt{(x _{2}-x _{1})^{2}+(y _{2}-y _{1})^{2}}\] given the points (x1, y1) and (x2, y2)
so plug in
x1 = 2 , y1 = -3 , x2 = 12 , y2 = 7
and solve, which will give you your distance :)

Answer 2

Okay one sec let me work it out

Answer 3

(12 -2) ^2 + (12 -(-3) ^2 right?

Answer 4

(12-2) ^2 + ((7) -(-3)^2
almost :)
and don't forget to square root it

Answer 5

I got 14.14 Did i do it right?

Answer 6

that is correct
but I'm thinking from the options you might want to keep it with the square root
so you got √200 = √(100*2) = √100 * √2 = 10√2

Answer 7

Yes so the answer would be B right?

Answer 8

yep :)

Answer 9

Thanks so much i couldn't have done it without you!!!

Answer 10

your welcome :)
glad I could help :D
