Which ratio is not equivalent to the other three?
a. 4/5
b. 12/15
c. 21/25
d. 28/35

c

Step-by-step explanation:

Simplify 12/15. It becomes 4/5

21/25 does not have a common factor, so it stays as 21/25.

28/35 has a common factor of 7, so it becomes 4/5

8

step-by-step explanation:

just put √(2) * √(32) into a calculator. that will make the answer be 8.

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.
