An 18 in. by 16 in. rectangular piece of cardboard is used to make an open-top box with a volume of 336 in. by cutting identical squares, of side length x inches, from each corner. A diagram is shown below. 3 ? 18 in. 12. A polynomial equation that can be used to determine the dimensions of the box is A. x(18– 2x)(16 – 2x) + 336 = 0 B. x(18– 2x)(16 – 2x) – 336 = 0 C. 2r(18–x)(16 – x) +336 = 0 D. 2r(18–x)(16 – x) – 336 = 0 16 in.

Two YouTube videos were uploaded at the same time - one is a video of a puppy and the other is a video of a kitten. The puppy video was watched 200 times right away, and 400 times per minute after that. The kitten video was watched 5 times right away, and the total number of views increased by a factor of 3 each minute after that. Find the function describing the view count of the puppy video, P, t minutes after it was uploaded. P(t) : Find the function describing the view count of the kitten video, K, t minutes after it was uploaded. K(t) Suppose you want to determine the minute when the kitten video will have more views than the puppy video.
