Question

I need help plz help me

Answer 1

B.
`√(116)`

Explanation:

Lenght of segment AB is the distance between A(-3, 1) and B(7, 5):

`AB = √((x_2 - x_1)^2 + (y_2 - y_1)^2)`

Let,

`A(-3, 1) = (x_1, y_1)`

`B(7, 5) = (x_2, y_2)`

`AB = √((7 - (-3))^2 + (5 - 1)^2)`

`AB = √((10)^2 + (4)^2)`

`AB = √(100 + 16) =`

`AB = √(116)`
