the side length of a square in feet is represented by z+6. find an expression for the area of a square.

(z+6)^2

Step-by-step explanation:

The area of a square is the product of the length times the width.  The lenght is equal to the width for a square, so (z+6)*(z+6) = (z+6)^2

[z^2 + 12z + 36]

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).
