Question

What is the distance between (4,2) and (-2,0) pythagorean therom

Answer 1

2sqrt(10)

Explanation:

sqrt[(0-2)² + (-2-4)²]

sqrt(4 + 36)

sqrt(40)

2sqrt(10)

Where,

sqrt: square root

Answer 2

sqrt(40)

Explanation:

The distance between two points can be found using

d = sqrt( (y2-y1)^2 + (x2-x1)^2 )

sqrt( (0-2)^2 + (-2-4)^2 )

sqrt( (-2)^2 + (-6)^2 )

sqrt( 4 + 36)

sqrt(40)
