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.
Answer: The answer is 1
Step-by-step explanation: The distance between -7 and -3 is 4 then half the distance in between -7 and -3 is going to be -5 because we just clarified that the distance between -7 and -3 is 4 so we did 4/2 and got 2 so we can figure out whats the distance between each point. Now that we figured that out we can determine what value the blue dot is if the value between each point is 2 then we can make out what the rest of the points on the line. If we from -3 to the blue point that would be 1.
3 hundreds equal to 300
17 tens equal to 170
13 ones equal to 13
1 tenths equal to 0.1
2 hundreths equal to .02 when added all together you'll get
483.12 <---- The answer
Answer:
-13
