Answer:


6√(5)

Explanation:

Thing of this like a right triangle and use pythagorean theorem.

You can see that the x-cordinate changes by 6 when you go from A to B so that means one of the legs of the triangle is 6.

You also see that the y-cordinate changes by 12 when you go from A to B so that means the other leg of the triangle is 12.

Next, use pythagorean theorem
6^2+12^2=c^2

You see that simplifies to 180 =
c^2 so then you take the square root of both sides.

c =
√(180) ; now you must simplify this.
√(36)×
√(5) which equals 6
√(5)

Final answer:
6√(5)
