A)
A polygon is a closed shape so there must be at least three sides. Therefore, the least value that n can be would be three.

Math riddle! Correct answer gets brainliest! Answer with what x and y are equal to.

RSB [31]

Answer:

$\displaystyle [9, 4\frac{1}{2}]$

Step-by-step explanation:

I figure these exercises out by numeric association. I see a 3, so I know right away that there might be a 9 somewhere. So, you start by plugging 3 in for $\displaystyle x,$ THEN plug $\displaystyle 1\frac{1}{2}$ in for $\displaystyle y$ sinse there are twise the quantity of $\displaystyle y$ than there are of $\displaystyle x.$ Now, doing so will give you $\displaystyle 24 ≠ 18.$ This tells you to try another pattern, so go with plugging $\displaystyle 4\frac{1}{2}$ in for $\displaystyle y$ and $\displaystyle 9$ in for $\displaystyle x$ . Doing so gives you what you are looking -- $\displaystyle 36 = 36.$ Therefore, the association wourked perfectly. ☑
