5x =61-6
5x= 55
X = 55/5
X = 11
I would represent that with a line graph.
You should get a positive number
Answer: 
Step-by-step explanation:
It is important to remember that the formula for calculate the area of a square is:

Where "s" is the side lenght of the square.
From the figure you can identify that the side lenght of the square can be represented with this expression:

Therefore, the following expression represents the area of the square:

In order to simplify it, you need to remember that:

Then, you get that the polynomial that represents the area of the given square, is:
