Answer:
d≈134.35
P Perimeter
380
Using the formulas
P=4a
d=2a
Solving ford
d=2P
4=2·380
4≈134.35029
Step-by-step explanation:
Answer:
m= -5/3
Step-by-step explanation:
y-y/x-x give you your slope
-4-1 = -5
3-0 = 3
-5/3 is -5/3
$48 because you have to find the totals for both then subtract
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
(5x10^4)+(3x10^3)+(8x10^2)+(0x10^1)+6x10^0)
