Area Rectangle = base x height = length x width = side1 x side2
= (6x + 4) (2x +11)
= (6x) (2x +11) + 4(2x + 11)
= 12x² + 66x + 8x + 44
= 12x² + 74x + 44
Part B) I don't know these terms but if I had to guess....... second degree and polynomial ???? possibly quadratic ????
Part C) Sorry, I don't know what the closure property is, so I can't explain how it demostrates it.
I can do the math, but I didn't know or have long forgotten the trival termonology. I looked up the closure property in Gaggle and I still don't understand it.
