Answer:
This series is divergent
F
Step-by-step explanation:
we are given a series
Firstly, we will find nth term
Numerator:
3, 4, 5,...
so, nth term will be

Denominator:
4,5,6,....
so, nth term will be

so, we can find it's nth term as

we can use divergent test

we can divide top and bottom by n


now, we can plug n=inf


Since, it is non-zero value
so, this series is divergent
Yes if x=5 then 4(5)= 20 and 15+5=20
Answer:
= (9 + h) /5
Step-by-step explanation:
One fifth means 1/5
Sum of 9 and h = (9 +h)
One fifth of sum of 9 and h = 1/5 x (9 + h)
= (9 + h) /5

Answer:
D)
Step-by-step explanation:
Because
a) 10 = 2(5) = 10
b) 10 = 5 + 5 = 10
c) 10 = 15 -5 = 10
d) 10 = 5 - 5 = 0 the result is not equivalent
