Given that a, b and c are positive integers, and abc=210, what is least possible sum for a+b+c

The least possible sum for a+b+c is 18.

Step-by-step explanation:

As given a,b and c are positive integers and abc = 210

So, let us consider some situation in which the product abc = 20

        abc = 210 & a+b+c = 18

       abc = 210 & a+b+c = 20

       abc = 24  & a+b+c = 24

        abc = 210  & a+b+c = 28

From all of the above situation the least sum is 18 when a, b and c are 5, 6 and 7 respectively.

$5.41

step-by-step explanation:

$20 - $14.51 = $5.49.

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.
