Plz help been stuck on this for awhile
Kazeer [188]

Answer:

<em>d</em> = \sqrt{74}  or 8.60

Step-by-step explanation:

(5, 8) (-2, 3)

Let 5 = x_{1}

     8 = y_{1}

     -2 = x_{2}

     3 = y_{2}

Plug in the values into the equation to get the distance:

<em>d = </em>\sqrt{(x_{2}-x_{1})^{2} + (y_{2}-y_{1})^{2}    }<em />

<em>d </em>= \sqrt{(-2-5)^{2} + (3-8)^{2} }

<em>d = </em>\sqrt{(-7)^{2} + (5)^{2}  }

<em>d</em> =  \sqrt{49 + 25}

<em>d = </em>\sqrt{74} or 8.60
