Answer:
(A)Third degree trinomial
Step-by-step explanation:
The given expression is:
Now, Degree of the expression is defined as the highest power of the variable given in the expression, thus in the given expression that is the variable is x and the highest power of x is 3, therefore it is a third degree expression.
Also, Trinomial is an expression which consists of three terms, and also the given expression consists of three terms that are
therefore, the given expression is a third degree trinomial.
Thus, option A is correct.

Answer:
Question 9: Variables: (smallest) s, q, r (largest)
Question 10: 5 whole numbers (7, 8, 9, 10, and 11)
Step-by-step explanation:
For question nine, there are two given statements... s=q-2 and q<r. Say we plug in 10000 (a really big #) in for q, then we would get s=9998 and r>10000. This way, we can see that s would be the smallest, then q, and r is the largest. <em>(q<r can be written as r>q)</em>

For question 10, it states . This can be split into
and
. When x is 12 in the first equation then
and when x is 6 in the second equation
(0.5 is also
). Therefore, x must be a whole number less than 12 and greater than 6, and it cannot be either 12 or 6. Whole numbers between 6 and 12 are 7, 8, 9, 10, and 11 or 5 whole numbers.
