Answer:

B. 5x+4

Step-by-step explanation:

Solving this is quite easy.

  1. Add 5x and 4 getting 5x+4
  2. Look at your bottom variables..since 7x and -7x are opposites they will cancel out! And same thing goes for y and -y.

I would like to know the process for dis ive been struggling on them. i tried to ask the teacher but they made it more confusing
Dafna11 [192]

Answer:

31.177 m

Step-by-step explanation:

So the formula of a hexagon is  Area = (3√3 s^2)/ 2

s = side in this problem.  A hexagon is made up of 6 equilateral triangles, so the distance from the center is equal to each of the sides.

For this problem, plug and chug.  Plug your knowns into equation and you will find the answer.

s^2 = (2√3)^2 = 12

Area = (3√3 x 12)/2 = 31.1769 m

I am not sure how many decimals you are supposed to round, probably 3 so in that case 31.177 m

Rearrange the formula A = \pi r ^ ( 2) for r
tatyana61 [14]
Consider re-writing this formula as "A = pi*r^2."  The backslash symbol "\" is unnecessary.

If A = pi*r^2, and we wish to solve for r, then divide both sides by pi:

A/pi = r^2

Taking the square root of both sides,   sqrt(A/pi) = r (r must be positive in this situation).
