what is the distance between point A and point B?

Answer:
[tex]d=\sqrt{45 }[/tex]
Step-by-step explanation:
To find the distance between 2 points, use the distance formula.
(2,3) (5,9)
[tex]d=\sqrt{(x2-x1)^{2}+(y2-y1)^{2} }[/tex]
[tex]d=\sqrt{(5-2)^{2}+(9-3)^{2} }[/tex]
[tex]d=\sqrt{(3)^{2}+(6)^{2} }[/tex]
[tex]d=\sqrt{9+36 }[/tex]
[tex]d=\sqrt{45 }[/tex]
[tex]d=3\sqrt{5}[/tex]
