Answer 1

Answer:

Your answer would be C because a trinomial consists of 3 parts!

Step-by-step explanation:

Answer 2

Answer:

$2x^3-7y^3 +14$

Step-by-step explanation:

Trinomial is a expression that has 3 terms. Now we check the options that has 3 terms.Terms are separated by operators like +,- , x or \

5xy has only one term

$2x-7$ has two terms 2x and -7. So it is not a trinomial

$2x^3-7y^3 +14$ has three terms 2x^3, -7y^3 and +14. So it is a trinomial.

$2y^2+7y$ has two terms, So it is not a trinomial
