find the distance between (0,0) and (3,4)

Question

the formula is d=the square root of x2-x1 +y2-y1 squared

Answer 1

If you remembered the Pythagorean Triple 3-4-5 you could have written down the answer immediately, 5.

Answer 2

The formula is d= √ [(x₂-x₁)²+(y₂-y₁)²]

d²=(3-0)²+(4-0)²=9+16=25  d=5
