Answer:
First, add, subtract, multiply, or divide within the parenthesis (if there are parenthesis). Then, you do the exponents. After that, you multiply and divide left to right. Finally, you subtract left the right.
Step-by-step explanation:
Order of Operations is also known as PEMDAS or Parenthesis, Exponents, Multiply, Divide, Add, Subtract. It means if we have an equation that is:
5 + 6 x 2, we do not add first. We multiply first, so we do 6 x 2, which gives us 12. 12 + 5 = 17 and that is your answer.

40 diamonds x 50 point (each diamond) = 2000 points
For this case we have the following polynomial:
![3x ^ 2 + 9x + 15](https://tex.z-dn.net/?f=3x%20%5E%202%20%2B%209x%20%2B%2015)
The standard form of the polynomial is given by:
![ax ^ 2 + bx + c](https://tex.z-dn.net/?f=ax%20%5E%202%20%2B%20bx%20%2B%20c)
Where, the axis of symmetry of the polynomial is given by the expression:
}
In this case we have:
![a = 3\\b = 9](https://tex.z-dn.net/?f=a%20%3D%203%5C%5Cb%20%3D%209)
Therefore, replacing values we have:
![x = - \frac {9} {2 (3)}](https://tex.z-dn.net/?f=x%20%3D%20-%20%5Cfrac%20%7B9%7D%20%7B2%20%283%29%7D)
Rewriting we have:
![x = - \frac {9} {6}\\x = - \frac {3} {2}](https://tex.z-dn.net/?f=x%20%3D%20-%20%5Cfrac%20%7B9%7D%20%7B6%7D%5C%5Cx%20%3D%20-%20%5Cfrac%20%7B3%7D%20%7B2%7D)
Answer:
The symmetry axis of the polynomial is given by:
![x = - \frac {3} {2}](https://tex.z-dn.net/?f=x%20%3D%20-%20%5Cfrac%20%7B3%7D%20%7B2%7D)
option C
Answer:
2n^3
Step-by-step explanation:
n^3 represents the cube of the number n; therefore,
"twice the cube of a number" is 2(n^3) or 2n^3
