Question 11
The expression 12x - 84 can be simplified as 12x - 2*2*3*7.
Factoring out a 2 from both terms, we get 2(6x - 42).
We can further simplify this by factoring out a 6 from both terms inside the parentheses, resulting in 2*6(x - 7).
This gives us the simplified form of the expression as 12(x - 7).
Therefore, the equivalent sum or difference is 12x - 7*12, which can also be written as 12x - 84.
Therefore, the correct answer is 12x - 84.

If Alvin loses 2 pounds per week, his weight after x amount of weeks can be represented by the expression 180 - 2x.
Explanation:
- Alvin's initial weight is 180 pounds.
- For every week, he loses 2 pounds. So for x weeks, he would lose 2x pounds.
- To find his current weight, we subtract 2x from his initial weight of 180.
- Therefore, the expression that represents his current weight after x amount of weeks is 180 - 2x.

To evaluate the expression ad + c^2b using the given values a = 10, b = 6, c = 3, and d = 5:
ad = 10 * 5 = 50
c^2b = (3^2) * 6 = 9 * 6 = 54
Therefore, ad + c^2b = 50 + 54 = 104.
The correct answer is 104.
ad = 10 * 5 = 50
c^2b = (3^2) * 6 = 9 * 6 = 54
Therefore, ad + c^2b = 50 + 54 = 104.
The correct answer is 104.
