Well, given that a quarter equals 5 nickels, we can reason that, in order to get 12 coins, we would have to get 10 nickels (equals 50 cents) and 2 quarters (the other 50 cents, to make a dollar).
You didn't say whether you needed this expressed in a mathematical formula, but knowing the answer already, it shouldn't be hard to come up with one if necessary.
Hope this helps.
The correct answer is C
3+ 0 is 3
3^2 + 0 is 9
Answer:
middle graph
Step-by-step explanation:
Soluton
The second (middle ) graph is the only one that works.
- First of all when you simplicity the right, you get y = x^2 - 1). That means that x does not go through 0,0. If you put x = 0 into x^ - 1 = 0, you get - 1. So on that basis alone both the first and third graphs are incorrect.
- Second, both xs in the factors are plus, so x^2 is plus, which means the graph opens upward.
The answer is 15,000,000,000,000
