step-by-step explanation:

`1234567890-=/*-qwertyuiop[]asdfghjkl; '\\zxcvbnm,./+ /

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150

c

step-by-step explanation:

there is vertical asymptote at x = 2 and x = 0

vertical asymptote occurs at the points where the denominator is 0. so we can say that

x = 2 occurs when there is a factor (x-2) in the denominator, and

x = 0 occurs when there is a factor "x" in the denominator

thus, the denominator of the equation would have "x * (x-2)", this is option c only. that's the correct answer.
