Which expressions are polynomials? select each correct answer. a.20x² + y b.20x2+y12 c.20x2y d.20x²

Step-by-step explanation:

Polynomial :  

An expression that can have constants (like 4), variables (like x or y) and exponents (like the 2 in ), that can be combined using addition, subtraction, multiplication and division, but:

no division by a variable.

a variable's exponents can only be 0,1,2,3,... etc.

it can't have an infinite number of terms.

Thus according to definition all are polynomials

A.20x² + y

B.20x2+y12

C.20x2y

D.20x²

b. 153 students do not participate in sports and seventy-five 12th graders were surveyed

●yes, this statement is absolutely apt.
