okay...? Anything in particular?
ABCD is a rectangle. Find the length of each diagonal. AC=2(x-3) BD=x+5
AC and BD are the diagonals, and diagonals of a rectangle are equal to each other 2(x-3) = x + 5 the first step is to solve for x, can you do that for me please?
How do I do that
first, look at the left side of the equation 2(x-3) distribute the 2 and tell me what you get
not quite, try again hint: A(B-C) = A*B - A*C
right! so the left side of the equation is 2x - 6 and the right side of the equation is x + 5 2x - 6 = x + 5 can you try solving for x now?
Do I subtract 6 to each side
add 6 to both sides, since we have -6 on the left side and we want to get rid of it
right, now subtract x from each side
right, x = 11, only one more step to go! let's use the equation from before, BD=x+5 if x = 11, what is x + 5?
great! that's our answer
Thank you! Could you help me with a few more?
how do I upload a pic on hete
Where is that
right under the box where you type stuff in
I'm on mobile I do not see it
Is that person online
Are they online
just a sec ^_^
I don't have that?
uh oh which iphone are you using? (or itouch?) or have you updated the app recently?
Do I have to be using the app I'm on the internet but I can get the app I'm on the IPhone 5s
ohhh yes! using the App would allow you to attach files :)
I'm getting it
I'm on the app now can you help me with a problem
Ok here's the pic
I suggest attaching the pic with the app then going back to the in browser (because the app is still a little slow)
interior angle of a square is 90 degrees 3y + 6 = 90
Is the answer 90?
not quite :) we have to solve for "Y" when given 3y + 6 = 90 you would first subtract 6 from both sides
Or is it 28
that's correct :)
Could you help me with a couple more
assuming this is a parallelogram?
just a parallelogram or square rhomus kite? does it say anything else? :3
It doesn't say but the topic is Special Parallelograms
ohhhh then it should definitely be a ... rhombus or something and the diagonals of a rhombus always bisect at 90 degree angles so if it really is a rhombus, then it should be 90 degrees ^_^
The answer is 90?
I believe so, if there is no other information given
It was right
diagonals in a rectangle are equal to each other so 2x + 4 = 6x - 20
subtract 2x from both sides
that's right! :) great job now add 20 to both sides
then divide both sides by 4
assuming angle 1 equals angle 2 there are 360 degrees in a quadrilateral 360 = 2*104 + 2*(2[angle 1]) 360 = 208 + 4 [angle 1] now subtract 208 from both sides
Divide by 4
that's what I got :)
So it's right
2(RZ) = (SW) 2(30) = 5x - 20
Is the answer 16
It was wrong
it was wrong and yet you still ask me? xD perhaps you should try opening a new question to get someone to help you I'm not actually good at these :-/
You've been getting them all right though
what I'm saying is idk how to do this one, sorry o-o
