For this case we have the following equation:
(3x + 4) ^ 2-36 = 15x + 20
We can rewrite the equation:
(3x + 4) ^ 2-36 = 5 (3x + 4)
Now we define the following variable:
p = 3x + 4
Substituting the variable in the equation we have:
p ^ 2-36 = 5p
Rewriting:
p ^ 2 - 5p - 36 = 0
Answer:
An equation that is equivalent in terms of p is:
p ^ 2 - 5p - 36 = 0
Answer:
Yes!
Step-by-step explanation:
28 - 4t = 3t
Isolate t:
28 = 7t
t = 28 / 7 = 4
I believe you are asking in how many ways they can sit. If so:
The 1st can sit anywhere: he has only 1 way to sit
The 2nd can sit in 11 ways, since one seat is already occupied
The 3rd can sit in 10 ways, since 2 seat are already occupied
The 4th can sit in 9 ways, since 3 seat are already occupied
The 5th can sit in 8 ways, since 4 seat are already occupied
--------------------------------------------------------------------------------
The 12th can sit in 1 way, since11 seat are already occupied
General formula for a circular table:
Number of ways they n persons can be seated: (n-1)!
and the 12 can be seated in (12-1)! = 11! = 39,916,800 ways.
This is called circular permutation
