Question

Which expression represents the word phrase three times the difference of a number and eight?
3 (n – 8)
3n - 8
3(8-n)

Answer 1

Answer:

3 (n-8)

Step-by-step explanation:

difference of a number and eight = n-8

3 times that = 3 (n-8)

Answer 2

Answer:3(n-8) or 3(8-n)

Step-by-step explanation:

For this question, given that the unknown number is n, the difference of that and 8 is with 8 - n or n - 8, that depends on n, if n is more than 8, then it is n - 8, 8 - n otherwise. But we do not know what n is so it is considered both. After that they said 3 times so it is 3(n-8) or 3(8-n)
