Question

Find the distance between (-4,8) and (4,4). Express answer in simplest radical form.

Answer 1

use formula for distance:\[d=\sqrt{(x1-x)^{2}+(y1-y)^{2}}\]

Answer 2

oh snap lol. can u help solve this?

Answer 3

in your case:
\[d=\sqrt{(4-(-4))^{2}+(4-8)^{2}}\]
solve it please... let me know if need help

Answer 4

\[d=4\sqrt{5}\]
do you see it?

Answer 5

kinda i got something totally off

Answer 6

let's try again:

Answer 7

i dont understand this process and i have more of these problems

Answer 8

\[d=\sqrt{8^{2}+(-4)^{2}}=\sqrt{64+16}=\sqrt{80}=\sqrt{16*5}=...\]

Answer 9

4 sqrt 5?
