A basketball court is in the shape of a rectangle. It has a length of (x - 7) meters and
a width of (x + 3) meters. The expression below represents the area of the court in
square meters:
(x - 7)(x + 3)
Which of the following simplified expressions represents the area of the basketball
court in square meters? (5 points)
1) - 6x + 3
2) x2 – 21
3) x2 - 4x – 21
4) x2 - 7x + 3

3)

Step-by-step explanation:

first you multiply the x that's in the first parenthesis by the x in the other parenthesis giving you x2

then you multiply that same x by the 3

you now have x2 + 3

Do the same with the -7

you should get x2 + 3x - 7x - 21

Combine like terms( +3x and -7x)

and you get

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.
