Answer:
= -27a^3+108a^2-144a+64
Step-by-step explanation:
Simplify:
=64-144a+108a^2-27a^3
=64+-144a+108a^2+-27a^3
Answer
= -27a^3+108a^2-144a+64
Use an equation:
x^9/x^6=64
x^(9-6)=64
x^3=64
x=4
note that x^9 means "x to the power of 9", same with other ones
the number is 4.
28/8 = 3 remainder 4 so 3 4/8(fraction) or 3 1/2
You would want to divide the minutes to the songs so you can find out how long one song is, but sense there was a remainder you could turn it into a fraction or you could keep diving. In this case you would want to stop. To find the fraction here is a formula the divisor is the denominator, the numerator is the remainder and the whole number is the number you get that is behind the remainder
