Suppose you have 48 feet of fencing to enclose a rectangular dog pen. The function A=24x-x^2, where x = width, gives you the are

Alecsey [184]

Answer:

Width: 12 ft

Maximum area: 144 ft²

Step-by-step explanation:

A = 24x – x²

A = –x² + 24x

A = –(x² – 24x)

A = –(x² – 24x + 144) + 144

A = –(x – 12)² + 144

Therefore, the maximum area of 144 ft² occurs at x = 12 ft.

LenaWriter [7]

Answer:

x = 14 inches

Step-by-step explanation:

The area of a square piece of paper is 200 square inches.

We need to find the point on the number line below represents the measurement closest to the side length of the piece of wrapping paper. It is shown in the attached figure.

Area of a square = x², x is the side length

$x=\sqrt{A} \\\\x=\sqrt{200} \\\\x=14.142\ \text{inches}$

x = 14 inches

So, the side length of the square is 14 inches. It is shown in point A.
