Answer: The dimensions are 10 2/3 feet by 5 1/3 feet (Ten and two-thirds and five and one third).

Step-by-step explanation: This is our system of equations:y=Lengthx=Widthy=2x2x+2y=32We can substitute the y value in the second equation by plugging in the first equation: 2x+2(2x)=322x+4x=326x=32x=16/3 or 5 1/3We can plug in this x value into the first equation to find the y value:y=2(16/3)y=32/3 or 10 2/3

Which polynomial function is graphed below?

Ket [755]

Answer:

Step-by-step explanation:

We know that the graph passes through the point $(1, 0)$ , since the line crosses the X-axis at $x = 1$ , so that means our equation has $(x - 1)$ in it. The graph also passes through the point $(-3, 0)$ , so the equation also has $(x + 3)$ in it.

This narrows it down to options C and D.

When a graph "bounces" off the X-axis at a point, like it does at $x = -3$ , this is called a "double zero", meaning two factors of the equation equal zero. This means that the graph has $(x + 3)^{2}$ , leaving us with option D.
