Answer:

1) d=25 2) d=2
√(2) 3) d=
13√(2)

Explanation:

$d=√((-2-1)^2+(-2-2)^2)\\ d=√((-3)^2+(-4)^2) \\d=√((-9)+(-16))\\d=√(-25) \\d=5$

$d=√((5-3)^2+(-4-(-6))^2)\\ d=√((2)^2+(2)^2) \\d=√((4)+(4))\\d=√(8) \\d=2√(2)$

$d=√((8-(-9))^2+(-7-0)^2)\\ d=√((17)^2+(-7)^2) \\d=√((289)+(49))\\d=√(338) \\d=13√(2)$
