MaKayla sells square frames of various sizes. To find the
area of a frame, she uses the formula A=\:s^2-\left(s-2w\right)^2A = s 2 − ( s − 2 w ) 2,
where s is the length of the frame and w is the width of the frame.
1. What does each term in the formula represent?
2. Find the area of a frame that measures 15 inches on each side and
has a width of 2 inches.
3. MaKayla charges 20 cents per square inch for her frames. How
much will she charge for a frame that measures 18 inches on each
side and has a width of 3 inches?

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?
