which polynomials are in standard form?\nchoose all answers that apply:\na 10 - n\nb 5n + 3n³ - 1\nc n + 4n²…

Explanation:

Step1: Recall the definition of standard form of a polynomial

A polynomial is in standard form when its terms are written in descending order of degree.

Step2: Analyze Option A

For the polynomial (10 - n=10 - 1\times n), the degree of the first term (10) (a constant) is (0) and the degree of the second term (-n) is (1). Since (0<1), it is not in standard form.

Step3: Analyze Option B

For the polynomial (5n + 3n^{3}-1), the degree of the first term (5n) is (1), the degree of the second term (3n^{3}) is (3), and the degree of the third term (- 1) (a constant) is (0). Since (1<3), it is not in standard form.

Step4: Analyze Option C

For the polynomial (n + 4n^{2}-7n^{3}), the degree of the first term (n) is (1), the degree of the second term (4n^{2}) is (2), and the degree of the third term (-7n^{3}) is (3). Since (1<2<3), it is not in standard form.

Answer:

D. None of the above
