Answer 1

your answers are B A D D 6

Answer 2

Answer: 1. B,  2.A,  3. C,  4. D  and 5.  6.

Step-by-step explanation:

1.  A binomial is a polynomial in which the number of terms is 2.  So, the correct option is  B. $c^2-16.$

2. A monomial is an algebraic expression having a single term, so the correct option is A. $12c.$

3. The descending order of the polynomial is C. $4x^2-3x+9.$

4. The descending order of the polynomial $-19x^2+2+4x^3-7x$ is $4x^3-19x^2-7x+2.$ So, the third term is D. $-7x.$

5. The descending order of the polynomial $7x^{3}y^{3}+4-11x^{5}y^{2}-3x^{2} y$ is $11x^{5}y^{2}+7x^3y^3-3x^{2}y+4$. So, the order of the second term is $3+3=6.$
