Which of the following equations is the formula of f(x) = x1/3, but shifted 4 units to the left and 4 units up?
A. f(x) = 4x1/3 + 4
B. f(x) = 4x1/3 - 4
C. f(x) = (x - 4)1/3 + 4
D. f(x) = (x + 4)1/3 + 4

First, we would need to figure out how many shelves are needed to build 1 bookcase. To do that, you would need to divide the number of shelves by the number of bookcases it can make. 
65 ÷ 13 = 5

Now we know, it takes 5 shelves to build a single bookcase.  The next step would be to find out how many shelves it would take to build 6 more bookcases.  To find the answer, you would multiply the number of shelves it takes to build 1 bookcase by the number of bookcases that need to be built. 
5 x 6 = 30

So, yes, 32 shelves would be more than enough to build 6 more bookcases.

I hope this helps!
