The answer is B. Object of preposition
Does this word describe something?
What in the sentence does this word describe?
How does it add something important to the story?
Answer: it could be a or c
Explanation:
A bc it says I and my and me
C bc it uses then, first, and later
I suggest u pick c though
First replace k with 4 and you get
5*4+6
now multiply 5*4 (order of operations) and you get
20+6
Now just add and you get
26
Hope this helped :)
