Answer:
17160
Step-by-step explanation:
first there are 13 options
then there are 13 - 1 that was chosen
then there are 13 - 2 that were chosen
then there are 13 - 3 that were chosen
so that's 13 options, then 12 options, then 11 options, and then 10 options
and in order to figure out all of the possibilties we mutiply the options so
13*12*11*10 = 17160
little further explaining of why this works:
we have a set of letters (3 in a set)
A B C
what are the possible combinations?
AB
AC
BC
BA
CA
CB
the answer is 6 which is also 3 * 2 * 1 = 6

Answer:
The value of n is 11 feet.
Step-by-step explanation:
Given that the area of rectangle from is A = length×width so we have to substitute the variables into the formula in order to find n :

Let area = 33,
Let length = n,
Let width = 3,




I would say the best estimate would be 9 because the real answer is 8.71 and if you round that to the 1 place the answer would be 9.
