Answer:
Answer explained below:Step-by-step explanation:
Part C: To show that the polynomials are closed under addition and subtraction, we need to demonstrate that the sum or difference of any two polynomials will result in another polynomial.
In Part A, we found that the total length of Side 1 and Side 2 is 2x^2 + 4 , which is another polynomial.
In Part B, we found that the length of the third side of the triangle is 5x^3 - 4x^2 +3x - 12, which is also another polynomial.
Since we were able to obtain polynomials for both the total length of Side 1 and Side 2 and the length of the third side of the triangle,
we can conclude that the polynomials are closed under addition and subtraction.
Answer:
side3 = 5x^3 - 4x^2 +3x - 12Step-by-step explanation:
Perimeter of triangle = side1 + side2 + side3
5x^3 - 2x^2 +3x - 8 = 3x^2 -4x -1 + 4x - x^2 + 5 + side3
5x^3 - 2x^2 +3x - 8 = 2x^2 + 4 + side3
Side3 = 5x^3 - 2x^2 +3x - 8 - 2x^2 - 4
= 5x^3 - 4x^2 +3x - 12
Therefore, side3 = 5x^3 - 4x^2 +3x - 12
Independent variable: the best method to get rid of them.
