Question

Using the Distance formula, how would you solve from these two points? What do you do with the radicals?
(√2,-7√3), (4√2, 8√3)

Answer 1

just plug them in and solve

Answer 2

i get √707 but that's not right

Answer 3

change in x √2 - 4√2 = -4√2
change in y -7√3 - 8√3 = -15√3
then square them
change in x: 32
change in y: 675
add them together you get 707

Answer 4

try
\[3\sqrt{77}\]

Answer 5

how did you get that?

Answer 6

from
\[\sqrt{2}\] to
\[4\sqrt{2}\] is
\[3\sqrt{2}\] and from
\[-7\sqrt{3}\] to
\[8\sqrt{3}\] is
\[15\sqrt{3}\]

Answer 7

square. add them together, and then take the square root

Answer 8

oh i subtracted wrong

Answer 9

got it. good luck

Answer 10

thanks
