HELP PLS I FORGOT LOL TYSM! Megan argues that (5m-3)+(2m+4) models the closure property. What reasoning could Megan use to argue that addition of polynomials is closed?

A.) The coefficients of the sum are whole numbers and the

sum is a polynomial.

B.) The coefficients of the product are integers and the product is a polynomial.

C.) The exponents of the sum are whole numbers and the sum is a polynomial.

D.) The exponents of the sum are integers and the sum is a polynomial.

E.) The terms in the expression are rational numbers in the sum is a polynomial.

A. The coefficients of the sum are whole numbers and the sum is a polynomial.

Step-by-step explanation:

The approach to demonstrate the closure property for the sum consists in defining what a polynomial is and demonstrate that the sum of two polynomials with integer coefficients is equal to a polynomial with integer coefficients. We proceed to show the proof below:

1) , Given

2) Definition of addition

3) Definition of substraction/Associative and Commutative properties

4) Distributive property/Definition of substraction

5) Definition of addition/Result

Hence, the coefficients of the sum are whole numbers and the sum is a polynomial. The correct answer is A.

1)is not similar since corresponding sides are not in the same ratio

2)are similar since corresponding sides are in the same ratio and corresponding angles are equal

hope it will
