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:
1/4 or 25%
Step-by-step explanation:
The probability for rolling an odd number is 50% or
because there are 3 odd numbers, (1, 3, 5) and 6 total outcomes (1, 2, 3, 4, 5, 6). 
The probability for rolling two odd numbers in a row is

So, the probability of rolling an odd number twice is 25% or
.
