C. An arithmetic sequence with common difference 6
You haven't provided any value, but I can tell you the solution set for the inequality.
First of all, expand both sides:

Add 3x to both sides:

Add 6 to both sides:

Which is of course equivalent to

Divide both sides by 9

So, every number smaller than 2 is part of the solution of this inequality.
Answer:
34
Step-by-step explanation:
(x + 12) + 100 + x = 180
2x + 112 = 180
2x = 68
x = 34
Answer:
B. (2x+4y)(4x2-8xy+16y2)
Step-by-step explanation:
hope this helps!
In order to find out what deal is better:
- We have to find the unit rate for each deal
- Total amount of paper towels ÷ The price
So it would be....
- 18 ÷ 14 = 1.285714
- 12 ÷ 10 = 1.2
Short Answer:
The better deal is 10 rolls of paper towels for $12.
Long Answer:
I wanted to find out the price per roll of paper towel for each deal so I created a unit rate problem which is the numerator divided by the denominator. From there, I was able to get my answers, compare which one was less than the other, and select the best deal.
Hopefully this helped >-<
