Answer: The length of the square is 
Step-by-step explanation:
By definition, the area of a Regular polygon can be calculated with the following formula:

Where "s" the length of any side of the polygon and "n" is the number of sides .
According to the information given in the exercise, you know that:

Since an hexagon has six sides, you know that:

Therefore, its area is:

The formula to find the area of a square is:

Where "s" is the length of any side of the square.
Since that regular hexagon has the same area as this square, you can substituting the area calculated above into the formula for calculate the area of a square, and then solve for "s".
Then you get:

Answer:
y = -1/3x -3
Step-by-step explanation:
-2x - 6y = 18
We want to solve for y since the slope intercept form is y =mx+b where m is the slope and b is the y intercept
Add 2x to each side
-2x-6y +2x = 2x+18
-6y = 2x+18
Divide each side by -6
-6y/-6 = 2x/-6 + 18/-6
y = -1/3x -3
This is in slope intercept form with the slope -1/3 and the y intercept -3
250 represents the initial amount of money she got from her birthday. 35 represents the amount of money she gains every month. m represents the number of months. 35m is the amount of money she gains after m months, without adding the initial amount of 250. Hope this helps!
go ask my sister for help her name is daryn 250406 or somthing like that
