Which term describes the polynomial 6 + 3x + 4y?

Linear trinomial describes the given polynomial.

Step-by-step explanation:

Given polynomial is 6 + 3x + 4y

Polynomial is described either by the number of terms and by the degree of the it.

Based on number of term. we have,

Monomial - polynomial having 1 term  

Binomial - polynomial having 2 term  

trinomial - polynomial having 3 term  

Based on degree of polynomial. we have,

Linear - when degree is 1

Quadratic - when degree is 2

Cubic - when degree is 3

Given Polynomial has 3 terms and degree = 1

So, it is Linear trinomial.

Therefore, Linear trinomial describes the given polynomial.
