Answer: 
Step-by-step explanation:
Let be "C" the circumference of the circle (in feet) and "r" the radius of the circle (in feet).
Based on the information provided in the problem, you know that the circumference of the circle is always
as large as its radius.
Notice that this indicates a multiplication. Then, this means that the circumference of the circle is always equal to
by "r".
Based on this, you can write the following formula that expresses the circumference "C" in terms of the radius "r":

Just for future reference always put ^ for exponents. The answer is y-6 though.
(y-4)(y-6) create that trinomial. You can prove that by using the FOIL algorithm
