III NEEDDD HEELLL WILLL MARK BRAINLIES PLLLEEAASSEE HEE Select the expressions (more than one) that are polynomials.
options:

−2x^3+2x+4

x^2/7+1

x^−3+4x

6x−x^3+4x^2

ok just calm down

Step-by-step explanation:

wait ill let you know in the comments

Polynomials cannot have division or a negative integer exponent.  

−2x^3+2x+4  is a polynomial

x^2/7+1 is not a polynomial (division operation)

x^−3+4x is not a polynomial (negative exponent)

6x−x^3+4x^2 is a polynomial

number one is the correct answer

step-by-step explanation: dogs and cats are mentioned, no other animals

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
