PLEASE HELP! WILL GIVE YOU BRAINLEST What is AB if A(0,0) and B(3, 4)

A. 4
B. 5
C. 3
D. 7

b

the answer is b

in order to solve for AB you need to use the pythagorean theorem by making a triangle with AB as one of the sides of the triangle.

plot each point A and B and connect it and connect point B with the x-axis, (3,0) You'll see athat a triangle has formed. All you have to do after that is apply the Pythagorean theorem.

the distance from A to the new point (3,0) is 3, the distance from the new point to B is 4. Line AB will be the hypotenuse.

Pythagorean therom is a^2+b^2=c^2

so 3^2+4^2=c^2

  = 9+16=25

square root the 25 and you get a 5.
