C. because x represents "a number" it reads, "the difference..." and difference means subtracting. Also how would you write twice a number? 2n, it basically means a number times two. But that's not all. You still have to subtract by 3 so its 2n-3.

What is the simplified form of the expression?

zimovet [89]

Answer:

7c^2d-7c+4d-10

Step-by-step explanation:

Start off with the term that has c^2 in it. 5c^2d + 2C = 7c^2d, then since you have multiple choice, the d value differs between the two answer choices that have 7c^2d so you can do +3d +d to get +4d to get the fourth answer choice.

To check your work, you can add/subtract each term to see if you get 7c^2d-7c+4d-10
