A rectangle has sides measuring (6x + 4) units and (2x + 11) units.

Part A: What is the expression that represents the area of the rectangle? Show your work. (4 points)

Part 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 1

Answer:

So the area of a rectangle is equal to both sides multiplied together so you get A=(6x+4)(2x+11). Next you need to multiply this out, that is multiply all terms in one bracket by all terms in the other bracket, this gives you A = 6x*2x +4*2x + 6x*11 + 4*11, which is then A=12x^2 +74x +44, thats part a done. The degree is simply the highest power in this case 2 and its called a quadratic equation. I think that's what is meant by classification (not sure)
