Question

Find the distance between A (6, -1) and B ( -18, 15)

Answer 1

28.8444102 or 28.8

Explanation:

distance between A (6, -1) and B ( -18, 15)

im just going to send a picture

I-18 + 6l = 24

l-1 + 15l = 16

24^2 + 16^2 = ?

576 + 256 = 832

the square root of 832 is 28.8444102 or 28.8

Answer 2

8√13 units

Explanation:

We use the distance formula.

The distance formula states that the distance between two points (x, y) and (a, b) is equal to:

d =
`√((x-a)^2+(y-b)^2)`

Here, x = 6, y = -1, a = -18, and b = 15. Plug these in:

d =
`√((x-a)^2+(y-b)^2)`

d =
`√((6-(-18))^2+(-1-15)^2)=√(24^2+(-16)^2) =√(576 + 256) =√(832)` = 8√13

The answer is thus 8√13 units.
