Answer:

z+1 , 6 + w and 2x^{4}+4 are polynomials.

Step-by-step explanation:

Given  : Expressions.

To find: Which expressions are polynomials.

Solution : We have given expression

Polynomial : A polynomial is an expression consisting of variables and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer.

So, z + 1  having variable z and contact 1 so, it is a polynomial.

6 + w is also a polynomial.

2x^{4}+4 is also a polynomial that has degree 4 .

But expression y^{2}-\sqrt[1]{y}+4 is not a polynomial because it has fractional exponent.

Therefore, z+1 , 6 + w and 2x^{4}+4 are polynomials.

c. G = 9.75 * X - 4500 - 4.25 * X

Step-by-step explanation:

With the data of the statement we can get a function. Let X be the number of pounds sold.

to. Monthly income

IT = 9.75 * X

b. Monthly expenses

GT = 4500 + 4.25 * X

c. Monthly Earnings (Monthly Income - Monthly Expenses)

G = 9.75 * X - (4500 + 4.25 * X)

G = 9.75 * X - 4500 - 4.25 * X
