Question

what is the distance between point A and point B?

Answer 1

Answer:

$d=\sqrt{45 }$

Step-by-step explanation:

To find the distance between 2 points, use the distance formula.

(2,3) (5,9)

$d=\sqrt{(x2-x1)^{2}+(y2-y1)^{2} }$

$d=\sqrt{(5-2)^{2}+(9-3)^{2} }$

$d=\sqrt{(3)^{2}+(6)^{2} }$

$d=\sqrt{9+36 }$

$d=\sqrt{45 }$

$d=3\sqrt{5}$
