Arectangle 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.

part b: what are the degree and classification of the expression obtained in part a?

part c: how does part a demonstrate the closure property for polynomials?

i got a and b i just need with c
here is what i got for a and b

part a: area equals length times width
equals (4x + 5)(3x + 10) equals 12x^2 + 55x + 50

part b: the degree is 2, it's a quadratic expression.

there has been genes found in the x chromosome of males that have been linked to [homo/hetero]sexuality. in addition to the reign of the x chromosome, a section of chromosome 8 has also been link to, "alot of ppl are so " these facts were proven true after a 2014 study of a gay male and his strait brother. according to newscientist.com,"chromosome 14 and is mainly active in the thyroid, but also the brain. called tshr, it makes a type of receptor protein that recognises and binds to a hormone that stimulates the thyroid. in this way, the gene plays an important role in controlling thyroid function. the fact that tshr seems to be involved in sexual orientation fits with evidence that thyroid function seems to be linked to sexuality."

in conclusion, "ppl are so gay" due to their genetics.

answer: its c because when it has a magnet next to it it will move away from the mixture. hope this
