Best ResponseYou've already chosen the best response.0The lengths of two sides of a triangle are shown below: Side 1: 5x2 + 2x  3 Side 2: 8x  3x2 + 2 The perimeter of the triangle is 2x3  5x2 + 4x  8. Part A: What is the total length of the two sides, 1 and 2, of the triangle? (4 points) Part B: What is the length of the third side of the triangle? (4 points) Part C: Do the answers for Part A and Part B show that the polynomials are closed under addition and subtraction? Justify your answer. (2 points)

Best ResponseYou've already chosen the best response.3for example 5x^2 and 3x^2 are like terms adding them gives 2x^2 now do the same with the 2 terms in x and the 2 numbers
