Answer:
120,960 ways
Step-by-step explanation:
Assuming that each piece is unique, then the order of each piece matters.
There are 9 pieces in total, there are 3 options for the first piece (3 piano pieces), and the remaining 8 pieces can be permuted. The number of possible arrangements is:
The program can be arranged in 120,960 ways.

Step-by-step explanation:
no
Answer:
- The constant in the expression is '8'.
Step-by-step explanation:
<u>The constant is a number with no variable multiplied with the constant. </u>
- In this expression, 7k has a variable 'k', which is not a constant.
- If we look at 8, we can tell that it has no variable multiplied. This is a constant.
- When we look at the 2lk and 3l, they both have variables 'lk' and 'l' respectively. They are not constants.
Hence, the constant in the expression is '8'.
Factor
36-n^2 is difference of 2 perfect squares
a^2-b^2=(a-b)(a+b)
6^2-n^2=(6-n)(6+n)
factor
n^2+16n+60
find what 2 numbers multiply to 60 and add to 16
factors of 60=2,2,3,5
the numbers are 10 and 6
so factored out
(x+6)(x+10)
(x+6)=(6+x)
so the equation is
[(x+6)(x+10)]/[(6+x)(6-x)]=[(6+x)/(6+x)] times (x+10)/((6-x)=1 times (x+10)/(6-x)
the answer is (x+10)/(6-x)
