Answer 2

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

Answer 3

use this

Answer 4

Distance formula between two poins P1(x1,y1) P2(x2,y2):
\[d(p_1p_2)=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\]

Answer 5

*+

Answer 6

im extermely sorry :)

Answer 7

it would substitute in as (5+4)^2 + (0-0)^2

Answer 8

\[d(p_1p_2)=\sqrt{(9)^2}\]

Answer 9

the reason why it is (5+4) is because 2 negatives make a positive

Answer 10

example:
\[b-(-a)=b+a\]

Answer 11

then (5+4)^2 would be 9^2
and
(0-0)^2 would be 0^2

Answer 12

9^2 would turn into 81
and
0^2 would turn into 0

Answer 13

81+0=81

Answer 14

then you will have to find the square root of 81

Answer 15

\[d(p_1p_2)=\sqrt{81}\]

Answer 16

which is 9

Answer 17

so your answer will be 9

Answer 18

\[d(p_1p_2)=9\]

Answer 19

yes correct :)
Good luck!!
