Answer:
m is greater in the end so the darker line should go right as it's increasing and starting from the 2
Step-by-step explanation:
We must find UNIQUE combinations because choosing a,b,c,d... is the same as d,c,b,a...etc. For this type of problem you use the "n choose k" formula...
n!/(k!(n-k)!), n=total number of choices available, k=number of choices made..
In this case:
20!/(10!(20-10)!)
20!/(10!*10!)
184756
The unit rate is 8 pounds per dog.
128 / 16 = 8
To find the area of this rectangle you multiply the length by the width, like so (x+2) x (2x+5) .
To find the perimeter of this rectangle you add all the sides using this equation,
(x+2)+(x+2)+(2x+5)+(2x+5) .
I^3 = i^(2+1) = i^2 x i -1 x i = -i
