ANSWER
The algebraic expression that is a polynomial with a degree of 2 is
![6 {x}^{2} - 6x + 5](https://tex.z-dn.net/?f=6%20%7Bx%7D%5E%7B2%7D%20%20-%206x%20%2B%205)
EXPLANATION
The degree of a term of a polynomial is the total sum of the exponents of the variables in each term.
The highest degree of the polynomial is considered the degree of the polynomial.
For first option,
![4 {x}^{3} - 2x + 10](https://tex.z-dn.net/?f=4%20%7Bx%7D%5E%7B3%7D%20%20-%202x%20%2B%2010)
the highest degree is 3.
The second option is,
![{x}^{2} - 8 {x}^{3} + 3](https://tex.z-dn.net/?f=%20%7Bx%7D%5E%7B2%7D%20%20-%208%20%7Bx%7D%5E%7B3%7D%20%20%2B%203)
This polynomial also has a degree of 3.
The third option is,
![6 {x}^{2} - 6x + 5](https://tex.z-dn.net/?f=6%20%7Bx%7D%5E%7B2%7D%20%20-%206x%20%2B%205)
This last option has a degree of 2.
Therefore the correct answer is option C.
Answer:
c,d?
Step-by-step explanation:
Answer:
c. 18
Step-by-step explanation:
First, you would find the total sum of the 60 numbers. The average is always the sum of the numbers divided by the number of numbers.
35*18=630
15*10=150
Now we do not know how many numbers the last group has. However, we can find it out doing 60-35-15 to see how many numbers are left. There would be 10 numbers left
10*30=300
630+150+300=1080
1080/60=18
Hence, the answer is C(18)
