So, you want to multiply, because it said about. Since the price is 9.25, and that is the price of one square foot, multiply the price by the amount of square footage.
<span>This characteristic of non-functions was noticed by I-don't-know-who, and was codified in "The Vertical Line Test": Given the graph of a relation, if you can draw a vertical line that crosses the graph in more than one place, then the relation is not a function.</span>
5x- SR 40= 0., add to the other side, 5x= SR 40. divide both sides by 5, x= SR of 8, or 2 SR 2
A=(3.14)r^2
A=(3.14)3^2
A=(3.14)9
A=28.26ft^2
Hope it helps and is correct :)
