You would have to divide 105 by 7 and get an answer then you times that answer by nine and get your answer

Answer:
Answer image is attached.
Step-by-step explanation:
Given rational expressions:
And the rewritten forms:
We have to match the rewritten terms with the given expressions.
Let us consider the rewritten terms and let us solve them one by one by taking LCM.
So, correct option is 3.
So, correct option is 1.
So, correct option is 2.
So, correct option is 4.
The answer is also attached in the answer area.
Figure 1
n=1→f(n)=f(1)=1
Options 2 or 3
Figure 2
n=2→f(n)=f(2)=5
With Option 2:
f(n)=f(n-1)+2n
n=2→f(2)=f(2-1)+2(2)
f(2)=f(1)+4=1+4→f(2)=5 ok
With Option 3
f(n)=f(n-1)+n
n=2→f(2)=f(2-1)+2
f(2)=f(1)+2=1+2→f(2)=3 No
Answer: Second option: f(1)=1; f(n)=f(n-1)+2n; for n>=2
