    A rectangle has sides measuring (4x + 5) units and (3x + 10) units. Part A: What is the expression that represents the area of the rectangle? Show your work to receive full credit. -- To find area you have multiply both sides together so (4x + 5) * (3x + 10) units which equals 12x^2 +55x+50. Part B: What are the degree and classification of the expression obtained in Part A? -- l the degree is the highest exponent, so 2 and classification would be a polynomial. Part C: How does Part A demonstrate the closure property for polynomials? -- I NEED HELP WITH THIS PART

    For part B, you can get more specific with the classification.

    the closure property is the idea if you take two numbers, and do some operation (eg: multiply) then the result will be in the same set example: take two integers, multiply them, the result is an integer. So we say the set of integers is closed under multiplication

    it extends to polynomials take any two polynomials multiply them the result is some other polynomial

    so the set of polynomials is closed under multiplication
