Answer 1

@Vocaloid

Answer 2

\[D = \sqrt (x _{2-} x _{1})^2 + (y _{2} - y _{1})^2\]

Answer 3

uh?

Answer 4

@bm717 what was that?

Answer 5

Ignore her. Do you know how to use the formula?

Answer 6

the distance formula?

Answer 7

Yes

Answer 8

It was a hand spasm I had this problem first ;-;

Answer 9

I tried doing the distance formula, and I came up with the wrong answer

Answer 10

Can you show your setup?

Answer 11

yes,

I did (-1-4) to the second power which would be -25

Answer 12

After you take -5 to the second power, the negative sign goes away

\[-5^2 = -5 \times -5 = 5 \times 5 = 25\]

Answer 13

then I did (1-(-5))to the second power, which would be 36

Answer 14

then I added 25+36=61

Answer 15

then I did the square root of 61, which is 7.8

Answer 16

I think I see your problem.

You need to do x1 - x2
x1 is -1
x2 is -4

-1 - (-4) = -1 + 4 = 3

Answer 17

so, it's 3 +36

Answer 18

Yes

Answer 19

Try that now

Answer 20
