Answer: The number of ballots increases by 3: 3x3=9, 9x3=27, 27x3=81...
After 10 cuts, there will be 59,049 ballots.
A quadratic with roots at 8 and 5 is f(x) = x^2 + 10x - 24
In order to find an equation given roots you can create statements that equal 0 in order to create parenthesis. For instance we know x = 8 at one point. So, we can solve that to equal 0.
x = -12 ----> add 8 from both sides
x + 12 = 0
We can do the same for the other zero.
x = 2 ----> subtract from both sides
x - 2 = 0
Now that we have both of these, we can multiply these two things together. This will give us the function we need.
f(x) = (x + 12)(x - 2)
f(x) = x^2 + 12x - 2x - 24
f(x) = x^2 + 10x - 24

What are the answer choices?
Step-by-step explanation:
Answer:
yes
Step-by-step explanation:
when 6 and 5 intersect it makes a ninty degree angle which is also known as a right angle and since its a triangle it simplifies to a right triangle. Sorry if i am wrong but im pretty sure im right lol
Answer:
15 lessons for $ 80
Step-by-step explanation:
In case 1
Cost of 1 lesson = $10
In case 2
Cost of 1 lesson = 40/5 = $8
In case 3
Cost of 1 lesson = 80/10 = $8
In case 4
Cost of 1 lesson = 80/15 = $ 5.33
Hence,
The best deal is case 4 i.e 15 lessons for $ 80
