Trey's : $20+ $0.80song
Deb's : $21 + $0.60 song

20+0.8s = 21+0.6s
0.8s-0.6s= 21-20
0.2s=1
then s = 1/0.2 = 5

so the monthly charge will be the same for both clubs for 5 songs.

and it will cost $20+$0.80(5)= $20+$4= $24.

The answer is Option B (x + 6)(x^2 + 8)

Step-by-step explanation:

Step 1: Group the given cubic polynomial into two sections.  

So  polynomial can be  grouped as

(x^3 + 6x^2) + (8x + 48)

Step 2:Find what's the common in each section.

In section (x^3 + 6x^2)  the come term is x^2

In section (8x + 48)  the come term is 8

Step 3:Factor the commonalities out of the two terms.

Factoring out x^2 from the first section  (x^3 + 6x^2), we get  x^2(x + 6)

Factoring out 8 from the second section(8x + 48) ,  we will get 8(x + 6).

Step 4: Combine the factors together for terms contains the same factor,

Combining we get,\left(x+6\right)\left(x^2+8\right)

\left(x+6\right)\left(x^2+8\right)
