Question

Find the exact distance between the points (7,-22)(-8,17)

Answer 1

Use the distance formula:\[d=\sqrt{(x_2-x_1)^2)+(y_2-y_1)^2)}\]

Answer 2

would d=1,551?

Answer 3

no

Answer 4

did you use the formula @Shane_B gave you?

Answer 5

Yes. d=1,746?

Answer 6

if P(7,-22) and Q(-8,17) then
\[ \LARGE{ d(P,Q)=\sqrt{(7-(-8))^2+(-22-17)^2}=\\
\sqrt{15^2+39^2}=\sqrt{1746}=... }\]

Answer 7

yes but 194 is not prime so you can find more of its prime factors

Answer 8

sorry you did it great

Answer 9

thanks so much for your help....so leave the 194 as is?
