Juno calculated the area of a square to be 4/9 square yard. Which shows the side length of the square?

Stella [2.4K]

$\bf \textit{area of a square}\\\\
A=s^2~~
\begin{cases}
s=side's~length\\
--------\\
A=\frac{4}{9}
\end{cases}\implies \cfrac{4}{9}=s^2
\\\\\\
\sqrt{\cfrac{4}{9}}=s\implies \cfrac{\sqrt{4}}{\sqrt{9}}=s\implies \cfrac{2}{3}=s$

PLZZZ HELP will mark brainliest!

Answer:

(3,8): No, (-1,-11): Yes, (2,7): Yes, (0,-6): No

Step-by-step explanation:

Basically, you just substitute x and y with the numbers given.

18x - 3y = 15

y = 6x - 5

(3,8):

18(3) - 3(8) = 15

54 - 24 = 30 It is not equal to 15, so it does not work.

y = 6x - 5

8 = 6(3) - 5

8 = 13 It is not equal to 8, so it does not work.

Therefore, (3,8) is not a solution.

Try this for every pair and you will find that (-1,-11) and (2,7) are solutions.

I hope this helps!
