Question

Use the distance formula to find the distance, to the nearest tenth, from S(5, −4) to W(−3, 7).

Answer 1

185

Explanation:

distance formula is d=√((x_2-x_1)²+(y_2-y_1)²

so it would be d=
`\sqrt{(-3-5)^(2) + (7-(-4))^(2) }`

where we see
`(7-(-4))^(2)` will turn into
`(7+4)^(2)`

`(-3-5)^(2) =64`

`(7+4)^(2) =121`

64+121= 185

Hope this helps...sorry if i'm wrong.
