Answer:
The third one
Step-by-step explanation:
a lot of triangled have a long base and equal smaller sides
thats a weird question though
The solution to the given equation is n=-5.
The given equation is 7n+6=4n-9.
The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.
Here, transpose 4n to LHS of the equation and 6 to RHS of the equation, we get
7n-4n=-9-6
3n=-15
n= -15/3
n= -5
Therefore, the solution to the given equation is n=-5.

song will be played at the beginning of
the show, one in the middle, and one at
the end. Tell how many different set lists
are possible. Then tell if the situation
involves permutations or combinations.
Answer:
1320 different set lists are possible
Step-by-step explanation:
We have a set of 12 elements (12 songs)
There can be NO songs repeatedly
The order of the songs is important because One song will be played at the beginning of the show, one in the middle, and one at the end.
So as the order of selection is important we must use permutations.
The formula for permutations is:
where n is the number of items you can choose and choose r from them
In this case we know that:
,
Then:
