What is the distance between the points(22,27) and (2,-10) ? necessary round your answer to two decimal places

Distance formula : sqrt (x2 - x1)^2 + (y2 - y1)^2
(2,-10)x1 = 2 and y1 = -10
(22,27)x2 = 22 and y2 = 27
now we sub
d = sqrt ((22 - 2)^2 + (27 - (-10)^2)
d = sqrt ((20^2) + (37^2))
d = sqrt (400 + 1369)
d = sqrt 1769
d = 42.059 rounds to 42.06 <==

Basic algebra equation. first set up your equation: divide out 9.and now you are left with 2x + 4 = 8.
