Answer:
Explanation:
The 5 is a constant.
The other 2 are products of numbers and variables. The -5 is a term. Even thought it is a constant, it will combine with neither one of the two terms in the trinomial.
4xy^2: This is a combination of a number (4) and 2 variables (x and y). The x and y are different. One of them (y) is squared but that does not change anything. It is still 1 variable. The x is another variable. So together, you have a produce of a number 4 - and 2 variables (x and y). Because this given question is a sum, 4xy^2 could also be classified as a term.
3x is also made up of a product of a number (3) and a variable (x). It is classified as a term, since it cannot combine with either of the other 2 terms.
