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)
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:
28
Step-by-step explanation:
It is 8 combination 4- using a TI 84, type in 8, then hit math- over to probability then nCr- then 6
You want to divide 0.60 by 3.
0.60/3=0.20
Each girl gets $0.20.
B = 7/8(A-9)
first you must distribute
B = 7/8A -7 7/8
add over the -7 7/8
B + 7 7/8 = 7/8A
now divide both sides by 7/8
B+7 7/8
----------- = A
7/8
Answer:
Angles
Step-by-step explanation:
A polygon is a shape, I don't think there are conversions since a polygon is not something you can measure. A population can be counted with normal numbers, 1,2,3... density is calculated with mass and volume, not radians and degrees.... yeah.
Angles are measured in radians and degrees, so it's angles.
