Answer:
All the sides of a rhombus are equal and opposite sides parallel and equal.
Therefore by understanding the above we can deduce that:
7x - 4 = 5x + 4
7x - 4 + 4 - 5x = 5x + 4 + 4 - 5x (Separate all the terms with x to go to the other side of the equals sign and do the some for the constants).
7x - 5x + (4 - 4) = (5x - 5x) + 4 + 4
7x - 5x = 4 + 4
2x = 8
2x/2 = 8/2
x = 4
In Middle School math, it means to find out what number ' x ' must be in order for the equation to be a true statement. In middle school, it can only be one number.
<u><em>Answer:</em></u>
<u><em>x = y - 8</em></u>
<u><em>1x + 5 + 8y = x + 8</em></u>

The factors would be (x-9)(x+4).
You can use the decomposition method to find this. I personally use the chart method so I do not necessarily know how to explain the decomp method in detail. However the idea and end goal are the same for both of them.
Try to find what multiplys to the last part of the polynomial but will add to the middle part.
To check your work/factors you can try multiplying/foiling them out again to see if you get your original polynomial.
