-why is 4x2y + 5xy classified as a 3rd degree binomial

Since both variables x^2 and y are part of the same term, we add their exponents together to determine the degree. 2+1=3, so the degree is 3.

It's a binomial because it has two terms.

To determine the correct degree and classification, see how many numbers are sectioned off by addition or subtraction signs. It could be a binomial, trinomial, or a polynomial. Once you found that, whatever the highest exponent is is the degree ( so if the highest exponent of a trinomial was 5, it would be called a fifth degree trinomial) The polynomial 4x^2y+ 5xy is a third degree binomial because there are 2 sections by one addition sign (Binomial). Then you calculate the highest exponent which is 2+1=3, so you get a third degree binomial.

Hope this helped.

the best buy, is the 4- kilogram bag of lollipops for $18.40.

step-by-step explanation:

i found my answer by dividing the cost of each bag by their respective weights.

14.88 divided by 2 = 7.44

17.29 divided by 3 = 5.77

18.4 divided by 4 = 4.6

24.4 divided by 5 = 4.88

by this, i found that the 4 kilo bag is the best buy.
