Translating into a mathematical equation:
n + n^2 = 72
Rewriting, n^2 + n - 72 = 0
Factoring, (n+9)(n-8) = 0
Solving for n: n = -9 or n = 8
You must check both answers before accepting one, the other or both.
Example: suppose we check out n = 8. Then 8 + 8^2 = 72 is true, and n = 8 is a solution. Is n = -9 a solution? Try it.
Given that the equation looks like: (8^1)0
This means that our first step is to do what is in Parenthesis. 8^1 is = to 0
This means our equation now looks like:
(8)0
When you multiply anything by zero, it becomes zero.
This means your answer should be A.0
3 times 4 =12 8 times 4=32
So 12:32 is the same as 3:8
15. true 16. false in my coculations.
In the top the "f(x)" equals 9, now they are asking you to add onto the 9 by 1 causing it to be 10. If you did the first few you would have noticed that it takes 9 in order to get to 5 from -4.
here are the answers btw:
