Answer:

B, D, E, and F

x = -6, 0 , 3, 7

Step-by-step explanation:

The zeros of a polynomial are the solutions to its factored set equal to 0. Using the zero -product property, you can set each factor of the polynomial equal to 0. Each one will solve to specific solution for it.

The polynomial has factors x, x-3, x+6 and x-7. Set each equal to 0 and solve.

x = 0

x - 3 = 0 has solution x = 3

x + 6 = 0 has solution x = -6

x - 7 = 0 has solution x = 7

The zeros of the polynomial are x = -6, 0 , 3, 7.

A​ person's rectangular dog pen for his dog must have an area of 200 square feet.​ Also, the length must be 12 feet longer than
kherson [118]

Answer:

width = 9.36 ft

length = 21.36 ft

Step-by-step explanation:

Let the width be x ft long. Then it follows that the length will be (x+12) ft long.

To calculate the area would then be

x(x+12) = 200

xx^{2} +12x=200x^{2} +12x-200=0

x = 9.36 ft or x = -21.36 ft

We take the positive answer. So the dimensions are

width = 9.36 ft

length =  9.36 + 12 = 21.36 ft
