Answer:
\mathrm{Domain\:of\:}\:x^3+3x^2-x-3\::\quad \begin{bmatrix}\mathrm{Solution:}\:&\:-\infty \:<x<\infty \\ \:\mathrm{Interval\:Notation:}&\:\left(-\infty \:,\:\infty \:\right)\end{bmatrix}
Step-by-step explanation:
The answer is C because you go down 1/2
Part a: ten books. because 3.75 equals 15/4 or 30/8. 10 3/8's fit into 30/8, so 10 books
part b: do basically the same thing and you will get 14 books though
