okay so

distance formula \[\huge\rm d=\sqrt{(x_2 -x_1)^2+(y_2-y_1)^2}\] plugin x's y's values :)

okay.
Nnesha
  • Nnesha
x's and y's \[\rm (x_1,y_1)(x_2 ,y_2)\]
anonymous
  • anonymous
\[d=\sqrt{?}(5-2)^2+(-4--3)\]
anonymous
  • anonymous
idk how to do that thing where it puts it in there lol
Nnesha
  • Nnesha
it's okay i know what you mean and yes that' right
anonymous
  • anonymous
no how to solve it
Nnesha
  • Nnesha
first solve the parentheses (5-2) and (-4-(-3)) and then take square
anonymous
  • anonymous
d= square root of 9+-7
Nnesha
  • Nnesha
-4-(-3) = ??
anonymous
  • anonymous
-7^2
anonymous
  • anonymous
lol hang on that would be
anonymous
  • anonymous
49
anonymous
  • anonymous
so d= the square root of 58
anonymous
  • anonymous
@Nnesha
anonymous
  • anonymous
which is 7.6
anonymous
  • anonymous
right?
Nnesha
  • Nnesha
no no no -4-(-3) first distribute -3 by negative sign and then combine them
anonymous
  • anonymous
uhhhhhh whhaa
Nnesha
  • Nnesha
|dw:1439994778548:dw| ther is invisible one so multiply negative one times -3 and then add -4 there is negative sign you can't remove the parentheses ntill u multiply it with negative on
Nnesha
  • Nnesha
one *
anonymous
  • anonymous
what the heck. never heard of that
anonymous
  • anonymous
so -12^2
Nnesha
  • Nnesha
you never heard that you should multiply negative one by -3
Nnesha
  • Nnesha
what negative one times -3 = ?
anonymous
  • anonymous
heck to the no
anonymous
  • anonymous
3
Nnesha
  • Nnesha
calm down.....
Nnesha
  • Nnesha
okay so |dw:1439994946005:dw|
anonymous
  • anonymous
-12
anonymous
  • anonymous
ha sorry
Nnesha
  • Nnesha
why did you multiply -4 by 3 ? subtract it's -4+3
anonymous
  • anonymous
-1
Nnesha
  • Nnesha
yep right so \[\huge\rm \sqrt{(3)^2+(-1)^2}\]
anonymous
  • anonymous
screw this. i got like 20 more of em to do. whates one thing you dont understand. i got a 90 in the class anyways
anonymous
  • anonymous
I've been trying to figure these out for like 2 years and I still have no clue.
Nnesha
  • Nnesha
3^2 is same as 3 times 3 and 1^2 is same as 1 times 1
Nnesha
  • Nnesha
take square of 3 and 1and then add them together that's it
anonymous
  • anonymous
so 10
anonymous
  • anonymous
then whatever the square root of 10 is
Nnesha
  • Nnesha
yes right!
anonymous
  • anonymous
yea.
