Answer 2

distance formula : d = sq rt ((x2 - x1)^2 + (y2 - y1)^2))

(-4,-12).....x1 = -4 and y1 = -12
(11, -6)...x2 = 11 and y2 = -6

now we sub
d = sq rt ((11 - (-4))^2 + (-6 - (-12))^2
d = sq rt ((11 + 4)^2 + (-6 + 12)^2
d = sq rt (15^2) + (6^2)
d = sq rt (225 + 36)
d = sq rt 261
d = 16.155 rounded = 16.2
