What is an expression for the distance between the origin and a point P(x, y)? d = 0 d is equal to zero.
d=x2+y2−−−−−−√ d is equal to square root of x squared plus y squared end root.
d=x2−y2−−−−−−√ d is equal to square root of x squared minus y squared end root. d=y2−x2−−−−−−√ d is equal to square root y squared minus x squared end root.
