Find the distance between the two points in simplest radical form.

sweet-ann [11.9K]

Answer:

3 $\sqrt{13}$

Step-by-step explanation:

Calculate the distance using the distance formula

d = $\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }$

with (x₁, y₁ ) = (- 9, 8) and (x₂, y₂ ) = (- 3, - 1)

d = $\sqrt{(-3-(-9))^2+(-1-8)^2}$

= $\sqrt{(-3+9)^2+(-9)^2}$

= $\sqrt{6^2+81}$

= $\sqrt{36+81}$

= $\sqrt{117}$

= $\sqrt{9(13)}$

= $\sqrt{9}$ × $\sqrt{13}$

= 3 $\sqrt{13}$
