What is the sum 1/2 + 2/5?

9/10

Step-by-step explanation:

just get a common denominator then multiply the top and bottom by the same number

1/2 *5 = 5/10

2/5 *2 = 4/10

5+4= 9

9/10

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.

6e14 is the answer.
