Question

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

Answer 1

Answer:
`√(45) =3√(5)`

Explanation:

To find the distance between 2 points use this formula:

`\sqrt{(x1-x2) ^(2) +(y1-y2)^(2) }`

rad[(2+4)^2+(5-8)^2)]

=rad[36+9]

=rad45

=3rad5

Answer 2

`3√(5)`

Explanation:

Use the distance formula:

`√((8-5)^2+(-4-2)^2)=√(9+36)=3√(5)`
