Answer 1

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 to receive full credit. (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 2

medal for part a and fan for part b

Answer 3

Do you know foil?
For A multiply \((6x+4)(2x+11)\)

Answer 4

ok one sec

Answer 5

12x^2+74x+44 is what i got

Answer 6

that's the answer for A.
For b the highest exponent is 2, so it's a quadratic

Answer 7

so the answer for b is quadratic

Answer 8

yes

Answer 9

can you help with c also

Answer 10

I never really know what they want for those. I know that polynomial are closed under multiplication, so they might just be to do the reverse \((2x+11)(6x+4)\) and show that you get the same answer from A.

Answer 11

ok thx

Answer 12

also what is the degree
