I hope this helps. Keep in mind the 1/3 is slope and the 3 is y-intercept.
Answer: Hm, this sounds a bit out of order I hope you use better grammar and please ask a question not a comment
By definition, a rectangle is:
Any four sided polygon (quadrilateral) that contains four right angles.
By extension, a square is:
Any rectangle where all sides are of the same, or equal, length.
<h3>So yes, a square is always a rectangle.</h3>
9+3=12
30+20=50
300+100=400
Then add.
12+50+400=462
<span>So 339+123=462</span>
Multiply -8 on both sides

n + 2 = 32 Subtract 2 on both sides
n + 2 - 2 = 32 - 2
n = 30
