What is the function rule for the perimeter p of a building with a rectangular base if the width w is two times the length l?
a.) p=2l b.) p=6l c.) p=6w

Step-by-step explanation:

The perimeter is the sum of all sides of the figure. In this case, the perimeter of the rectangle would be: ; where is width, and is length.

According to the problem, the width is two times the length:

Replacing this relation in the perimeter equation, we have:

Therefore, the perimeter is six times the length of the rectangle. The correct answer is B.

step-by-step explanation:

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
