Answer: 2.12 × 
The coefficient (in green) will be 2.12
Step-by-step explanation:
Scientific notation is written by multiplying the number by a power of 10. This number is a number between 1 and 10.
Since this is a smaller number, we will be multiplying it by a power of 10 to a negative number.
To get this value to a number between 1 and 10, we must multiply it by 10 3 times (also shown as 10³) which gives us 2.12.
To get back to the original value, we multiply this by . This gives us our answer.
To find the domain, we find every single value that can exist along the x axis.
One can notice here that w is in the denominator, which means a value doesn't exist at 0, because we can't have 0 in the denominator.

Answer:
1) D. 
2) E. The coefficient of 
is -16.
Step-by-step explanation:
1) A polynomial is an algebraic expression of the form 
, where 
is the grade of the polynomial. In this case, the only equation that satisfies this definition is:
Correct answer: D
2) Let 
, we proceed to expand the expression by algebraic means:
We see that coefficients for 
and are -16 and 0, respectively. Hence, the incorrect answer is E.
Answer:
126in
Step-by-step explanation:
6*5=30
5*3=15
6*3=18
30+15+18 = 63
63*2=126
