Using the Pythagorean theorm, 
a^2 + b^2 = C^2, where a nd b are the side lengths and c is the hypotenuse ( diagonal line)

If it was a square both sides would be the same length so we would have:
13^2 +13^2 = c^2
169 + 169 = c^2
338 = c^2

c = SQRT(338) = 18.38

18.38 is larger than the 15.26 given in the problem , so the room is not a square.

The cost of performance tickets and beverages for a family of four can be modeled using the equation 4x + 12 = 48, where x
Hunter-Best [27]

For this case we give as data the following equation:

4x + 12 = 48

Where "x" represents the cost of a ticket.

By clearing the value of "x" of the equation we can know the cost of a ticket.

If we subtract 12 from both sides of the equation, we have:

4x = 48-12\\4x = 36

If we divide between 4 on both sides of the equation:

x = \frac {36} {4}\\x = 9

Therefore, the cost of a ticket is $ 9.00
