There is 3.28084 feet in a meter
Answer:
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) ![(5\cdot m +2\cdot m ) +[(-3)+4]](https://tex.z-dn.net/?f=%285%5Ccdot%20m%20%2B2%5Ccdot%20m%20%29%20%2B%5B%28-3%29%2B4%5D)
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.

The domain of the function where the function is decreasing is (-∞, 1). Then the correct option is D.
<h3>What are domain and range?</h3>
The domain means all the possible values of the x and the range means all the possible values of the y.
The function is given below.
f(x) = x² - 2x + 5
The equation can be written as
f(x) = x² - 2x + 1 + 4
f(x) = (x - 1)² + 4
Then the domain of the function where the function is decreasing will be (-∞, 1).
Then the correct option is D.
More about the domain and range link is given below.
