we can tell a rectangle is also a square when both width and length are the same,
then,
![x+1=x+3](https://tex.z-dn.net/?f=x%2B1%3Dx%2B3)
solve for x
![\begin{gathered} x-x=3-1 \\ 0\ne2 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20x-x%3D3-1%20%5C%5C%200%5Cne2%20%5Cend%7Bgathered%7D)
there is not solution, then the rectangle shown is not a square
<u>Kaifeng Montez can buy:</u>
8-slice Pepperoni pizza for $15.92
or
12-slice pizza for $22.32
One slice of Pepperoni pizza is $15.92 ÷ 8 = $1.99
One slice of the second brand pizza is $22.92 ÷ 12 = $1.86
So a piece of the second brand pizza is cheaper that a piece of Pepperoni pizza.
The second brand pizza (12-slice pizza) therefore is a better deal.
