B) 9ft

The area of a square is us found by taking the length of a side and squaring it. For example, if 9 is the side length, we would find the area by doing 9^2 or 9 x 9. This gives us 81 which is the closest to 76.5.

How to solve 1/4-x=x/8
Contact [7]

Answer:

x=\frac{2}{9}

Step-by-step explanation:

\frac{1}{4}-x=\frac{x}{8}

  • With the equation's current format, we will have trouble solving with all these fractions. Especially the fraction \frac{x}{8} is very difficult to deal with, so my first step would be:

(\frac{8}{1})(\frac{1}{4}-x)=\frac{x}{8}(\frac{8}{1})

  • If we multiply both sides by this number, we will be able to get rid of the messy fraction on the right side as well as remove the fraction on the left side. Like so:
  • <em>I put the 8 I multiplied onto each side in fraction form simply for clarity. You do not need to do this.</em>

(\frac{8}{1})(\frac{1}{4}-x)=\frac{x}{8}(\frac{8}{1})\\\frac{8}{4}-8x=\frac{8x}{8}\\2-8x=x

  • After this point, let's put our variable, x, onto one side of this equation and any other integers on the other by adding and subtracting them from both sides.

2-8x=x\\-9x=-2

  • Now we divide so that x is isolated, and we are done.

x=\frac{-2}{-9}=\frac{2}{9}

i would probably say the first option. you basically want to use the 2 points that are outside of the majority of all of the other points. in this case, i am pretty sure it would be the first option. i am not 100% sure, but i think that's the correct answer :)
