Question

Which expression gives the distance between the points (2, 5) and (-4, 8)?

Answer 1

answer is A

Explanation:

just took the test

Answer 2

D between points (x1,y1) and (x2,y2) is

`D= √((x2-x1)^2+(y2-y1)^2)`
given
(2,5) and (-4,8)


`D= √((-4-2)^2+(8-5)^2)`

`D= √((-6)^2+(3)^2)`

`D= √(36+9)`

`D= √(45)`
D=(√9)(√5)
D=3√5
