Answer:

2(n-9)

Step-by-step explanation:

Hi there!

Let "a number" = n.

"The difference" translates to subtraction, so when the question tells us "the difference of a number and 9", it translates to "n-9".

"Twice" means we'll be doubling something. In this case, we're doubling "n-9":

2(n-9)

I hope this helps!
