ANSWER
Step-by-step explanation
The product of a number and 8 is: 8n. 3 less than that product is 8n - 3
The difference of 8 and a number is (8 - n). 3 more than that is 3 + (8 - n)
The difference of a number and 8 is (n-8). 3 times that is 3(n-8)
The sum of a number and 8 is (n + 8). 3 times that is 3(n+8)
