Answer:
Step-by-step explanation:
Two sheets will cost: $27
The value of the first sheet will be $18, and since the other sheet is half off it will be half of the original value: 18 * 0.5 = 9.
Then you add the values together: 18 + 9 = 27.
Six sheets will cost: $81
For every sheet that is the original value there is a sheet that is half off. So since there are six sheets, 3 of the sheets will be $18 and three of them will be $9. We already know that 18+9=27, so just multiply that value by 3.
27*3= 81
Better deal: The second example
In the second example sheets are 30% off. 30% of 18 is $6. Subtract that value from 18 and you will get $12. In the second example one sheet is $12.
If we multiply that value by 2, we will get $24.
In the first example, two sheets costs $27, while in the second example two sheets cost $24. Since the cost is less for the second example, the second example is the better deal.

Answer:
A
Step-by-step explanation:
That's the formula for the solution of a quadratic equation, like this:
The formula is:
In your case:
The only answer that has c = -2 is the first one, A.
If you move the 5 to the left-hand side, it becomes -5 and with the +3 gives a -2.
