The length of a rectangle is represented by the polynomial 2x3 – 5x2 + 8 and the width is represented
by the polynomial x + 3. complete the following statements about the polynomial that represents the
area of the rectangle.

Step-by-step explanation:

We know that the area of a rectangle is:

And, givens are:

Replacing given expression:

So, to find the area, we need to solve that expression. The faster and easier way to do it is by graphing, given values to x-variable, and finding values for y-variable in return. Each pair represents a point. The graph is like the image attached.

In the graph, we observe that only has two solutions:

Now, we test each one to find an area that make sense, that is, a positive area:

We see that -3 makes the width zero, which don't make sense. So, we use -1.06, or just -1.

Therefore, the area is A=(2)(1)=2 square units

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .

the answer is 24
