Answer 1

plz hurry-

Answer 2

Is this a test?

Answer 3

no im just trying to get my grade up to a b

Answer 4

TnT

Answer 5

no one is coming to help meh

Answer 6

Do you know the distance formula?

Answer 7

no

Answer 8

\[d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\]

Answer 9

You have
\[x_1=4.2,y_1=-2,x_2=-5.2, y_2=-2\]
Substitute and solve

Answer 10

ok :)

Answer 11

thank u

Answer 12

No problem. Let me know if any difficulties.

Answer 13

ok :)

Answer 14

I should have mentioned an easier method. Since y-coordinates are same, you just measure the difference of x- coordinates:
d = |-5.2 - 4.2|
