The base of a triangle measures (3x − 6) units and the height measures (2x + 4) units.Part A: What is the expression that represents the area of the triangle? Show your work to receive full credit. (4 points)Hint: Area = 0.5bhPart B: What are the degree and classification of the expression obtained in Part A? (3 points)Part C: How does Part A demonstrate the closure property for polynomials? (3 points)

Answer With Step-by-step explanation:Part A: .5[ (3x – 6) (2x + 4) ] .5(6x^2 - 24) 3x^2 - 12 Part B: Second Degree Binomial Part C: For Part A, a polynomial was multiplied by another polynomial. The resulting product was a polynomial. This is a demonstration of the closure property for multiplying polynomials.
