Question

What is the distance between point A and point B?

Answer 1

Answer: Start with: c2 = a2 + b2

Put in the calculations for a and b: c2 = (xA − xB)2 + (yA − yB)2

Square root of both sides: c = square root of [(xA-xB)^2+(yA-yB)^2]

Step-by-step explanation:

Answer 2

Answer:

the answer is B. The square root of 45.

Step-by-step explanation:

use the pythagorean theorem.

1. Find the side lengths of A  and B, since you're trying to find the hypotenuse.

2. $A^{2} + b^{2} =c^{2} \\3^{2} +6^{2} =c^{2} \\9+36=c^{2} \\45=c^{2} \\c=\sqrt{45}$
