Answer:

D; "the sum of three times a number and six, divided by the difference of seven times the number and nine."

Step-by-step explanation:

"the sum of three times a number and six.."

the sum means addition, and it says that it is adding of 3 times a number plus 6. That 'number' is represented as 'p' since we don't know it.

"...divided by the difference of seven times the number and nine."

Since it said divided, we know that there is a denominator (something under the fraction line). On top of the fraction like is 3p + 6, this is called the numerator. That something under the fraction line, is seven times a number which is represented as 'p'. This is 7p is subtracted by 9.
