144 ways because 12 songs 12 ways 12*12
12 +4m = 24
4m = 12
m = 12/4
m = 3 so choice C. is right sure
To find sales tax on something, multiply the percent of the tax by the price of the item.
If you're not sure, begin by looking for any divisor that will divide into 24a^3c and 3a without leaving a remainder. Note that 3 is such a number, and a is another.
Factoring out 3a from 24a^3*c and 3a, we get 3a{8a^2*c, 1}
So the GCF is 3a.
Cuz They Are Identical Duhhh
