Hey, there!
The word "distance" means "subtract:"
For A: The question isn't asking the distance of [tex]15 [/tex] & [tex]-18[/tex] (So, this cannot be your answer) (it would give you the result of [tex]33[/tex] )
For B: The question isn't asking the distance of [tex]15[/tex] & [tex]18[/tex] (so this isn't answer) (it would give you a result [tex]-3[/tex] )
For C: It's not asking for the distance of [tex]18 [/tex] and [tex]15 [/tex] because it would give you the outcome of a [tex]3[/tex] (so, this isn't your answer)
For D. it is doing what the question is asking so this would most likely be your answer. The answer would be (if we solved it) [tex]-33[/tex]
Answer: [tex]OptionD.[/tex]
Remember to break down the words (or numbers) it will come in handy for the future
Good luck on your assignment and enjoy your day!
