The length of the patio is: 8x + 2
The given parameters are:
The perimeter of a square is:
So, we have:
Divide both sides by 4
Hence, the length of the patio is: 8x + 2

The minimum number of bicycles that must be produced and sold to break even = 20
Explanation:The profit generated by producing and selling n bicycles per week is given by the formula:
To get the minimum number of bicycles that must be produced and sold to break even, let P(n) = 0 (Since break even means no profit is made)
Solve the resulting quadratic equation above
This means that, to break even, either 60 or 20 bicycles must be produced and sold
The minimum number of bicycles that must be produced and sold to break even = 20
