Need quick with 2 math questions asap!

So remember that terms are groups of numbers and variables separated by + and - , and the degree of a polynomial is determined by the total power of the greatest term.

Starting with the first question, the correct answer is B. 3rd degree polynomial with 2 terms. The total power of the greatest term (2x^3) is 3, which makes it 3rd degree, and there are 2 terms (2x^3 and -4).

Now the second question's correct answers are A and D. To write a polynomial in standard form, you just need to combine like terms and rearrange the terms so that it's in descending order of degree. And this polynomial has two terms, 3x^4 and -1.

relating to or denoting a system of numbers and arithmetic based on the number ten, tenth parts, and powers of ten.
