Determine which expressions are polynomials. explain your reasoning.

For this case we have that a polynomial is of the form:

Where:

a, b, c, d, e, f: They are the coefficients

n, n-1,3,2,1: They are the exponents, where n is to the degree of the polynomial because it is the largest.

x: It is the variable.

So, we have to:

is a polynomial of degree 5.

answer: 4 meters

step-by-step explanation: to you understand 2/3 better you can do 1 divided by 3 = . then multiply that by the 2 which is .66666666666666667 then you would do 6 x .66666666666666667 which is 4.      

hope this .
