Because we are dealing with area, we have to square the difference of the 2 polygons.40 / 15 =

Answer:

Step-by-step explanation:
We begin with the equation 
In order to get x on the left side, we need to square root both sides. As we are taking the square root of each sides, one of the sides must have a ± added to it in order to make sure that both of the solutions are found.
± 
We can then simplify this
± 
And once more
± 
Which means that our solutions are

You can look for a factor of a 3 or 5 within the values 16 and 24.
24 can be factored as 3*8.
So you can break up the 24 in that way before multiplying,
and then have the 3's divide evenly out,
leaving you with a simpler problem.

Is this what you were looking for perhaps?
Step-by-step explanation:
n(-2) = -1 -(-2) + 4 = -1 + 2 +4 = 5
n(0) = -1 -0 +4 = 3
n(5) = -1 -5 +4 = -2
the answer is 18 hours
there are 48 hours in 2 days
1/8 of 48 is 6
3/8 of 48 is 18 because 6x3= 18
hope this helps
