you suppose to find the problem to that rhombus because it's a parallelogram
Astrophysics
  • Astrophysics
This isn't a very clear image, so is it like this then |dw:1440156635413:dw|
youngnephew34
  • youngnephew34
no
youngnephew34
  • youngnephew34
|dw:1440156729213:dw|
youngnephew34
  • youngnephew34
like that
Astrophysics
  • Astrophysics
Ok but is the rest correct? Like the right angles
youngnephew34
  • youngnephew34
yes
youngnephew34
  • youngnephew34
|dw:1440156895178:dw|
youngnephew34
  • youngnephew34
yes but the 8 goes on top and the 2x goes on the bottom
Astrophysics
  • Astrophysics
I don't know what you mean
youngnephew34
  • youngnephew34
and the 3x goes on your right side and the w 12 goes on the top right corner
youngnephew34
  • youngnephew34
ok Imma show you
youngnephew34
  • youngnephew34
yes correct
youngnephew34
  • youngnephew34
you know doing 90 degrees angle this is parallelogram of property
Astrophysics
  • Astrophysics
Well actually there is something wrong because then these aren't triangles
youngnephew34
  • youngnephew34
so you know how they do distributive of property but this is like that but only different
Astrophysics
  • Astrophysics
Can you just take a screen shot of your problem
Astrophysics
  • Astrophysics
Rhombus is a kind of parallelogram, I just don't really understand your image
youngnephew34
  • youngnephew34
youngnephew34
  • youngnephew34
there you go
youngnephew34
  • youngnephew34
did you see the image
Astrophysics
  • Astrophysics
Yeah ok I see, I haven't done this since I was in junior high so lets see...
youngnephew34
  • youngnephew34
TBH tho I thought it was 4
youngnephew34
  • youngnephew34
Is that the correct answer
phi
  • phi
the diagonals of a rhombus bisect each other you can write 8= 2x
phi
  • phi
also, 3x=12
Astrophysics
  • Astrophysics
Or yeah haha just go with phi, I'm stupid when it comes to geometry xD
youngnephew34
  • youngnephew34
ok
youngnephew34
  • youngnephew34
so how do you do that cause I did it different
phi
  • phi
if you use 2x= 8 divide both sides by 2, like this \[ \frac{2x}{2} = \frac{8}{2} \] or \[ \frac{2}{2}x = \frac{8}{2} \]
phi
  • phi
on the left side 2/2 is 1 and 1 times x is x what do you get on the right side?
youngnephew34
  • youngnephew34
ok now I see but it's still the same answer I got 4 right
Astrophysics
  • Astrophysics
Yeah I had got 4 as well haha
phi
  • phi
yes, x=4 but you should be learning how to get the answer... it is not the answer that counts, it is learning how to get it. if you use 3x=12 divide both sides by 3 \[ \frac{3x}{3} = \frac{12}{3} \] what do you get for x?
youngnephew34
  • youngnephew34
yea I did mines as 3x+12=2x+8
phi
  • phi
you can't say that. the diagonals are not the same size
phi
  • phi
if you get x=4 doing that, you "lucked out"
youngnephew34
  • youngnephew34
I consul out the x and the 3x-2 =1x 1x+12=8 subtract both sides gives mi 1x=4 x=4
Astrophysics
  • Astrophysics
|dw:1440158336109:dw| this is what I had originally as they bisect 3x=12, 2x = 8 @youngnephew34 bisect literally means to divide in two equal sides.
phi
  • phi
1x + 12= 8 1x + 12-12 = 8-12 x= -4 so you don't get x=4
youngnephew34
  • youngnephew34
nvm
youngnephew34
  • youngnephew34
I got 2 more I want you guys to check
phi
  • phi
we know x=4, and so we can figure out one of the diagonals is 16 and the other diagonal is 24 18 does not equal 24 but that is what you are saying if you write 2x+8= 3x+12 <-- not true.
youngnephew34
  • youngnephew34
ok
