Given:
A figure.
and 
To find:
What kind of figure and the value of x
Solution:
All four sides are congruent.
Diagonals bisect each other.
There the given figure is rhombus.
Diagonals bisect the angles.
⇒ 

Subtract 3 on both sides.


Subtract 6x from both sides.


Divide by 3 on both sides.


The value of x is
.
I think it's another trick question and the answer is 2000.
Answer:
vertex: (-1,25)
aos; -1
left x int: -6
right x int: 4
(not sure)
range is less than of equal to 25
If you see that 3x-3 and set it equal to x+7 then you will get this,
3x-3=x+7
Now solve for X. You will get 5.
Then you plug five in and get 12 For both sides and then multiply 12 by 4 and get 48.
You answer is 48.
Hope this helps you.
What can be used on this is the distance over time formula, so what you,do is divide 228 by 4 to get the distance traveled in one hour. And 288/4=57. So they traveled 57 mi in one hour. Hope this helped.
