Determine the degree of the polynomial: –3.1ax^4+2.5ax+2ax^4+1.1ax^4–0.5ax– 2ax

Degree = -1*

Step-by-step explanation:

The degree of a polynomial is its greatest exponent among all its terms.

To begin we group equal terms and solve the sums.

Resolving the sums we have to:

P (x) = 0

This polynomial is considered a null polynomial.

There are several opinions about the degree of a null polynomial.

Some books consider it as -infinity, others say it is not defined.

On the other hand, some assign a grade -1 by convention *

the area of the rectangle is 35units^2.

step-by-step explanation:

graph it and find the distance.

it is a 5*7 rectangle.

therefore the area is 35units^2.
