Answer 5

(x1,y1)=-1,-3
(x2,y2)=11,7
Put the values in the formula and try doing it.

Answer 6

Answer 7

i did
i got square root of 244? is that right???

Answer 8

Let me do it now.

Answer 9

Do you have options?

Answer 10

no

Answer 11

ok let me know and maybe you can explain where i screwed up

Answer 12

Yes under root 244 is right :D

Answer 13

(-1,-3); (11,7);

-1 -11 = -12 , (-12)^2 = 144

-3 -7 = -10 (-10)^2 =100
add and get
244
sqrt(244) is the answer. Looks like you did it correctly

Answer 14

hmm but i got it wrong when i put that. is there a way to simplify that

Answer 15

@phi o_O you're coool,no? *heavy sarcasm*

Answer 16

right away we can write 244 as 2*122 = 2*2*61 so 2 sqrt61)

Answer 17

you mean 4?

Answer 18

sqrt(4*61) = 2 * sqrt(61)
