Answer: D. 
Step-by-step explanation:
Using exponent rules an exponent to the power of a number will multiply by each other.
So the -4 and -9 will multiply.
The 6 in the numerator will now have a positive exponent of 36.

Now we can divide and when we do so the exponents will subtract from each other.
So 36 - 6 = 30
And the base of 6 does not change.
The simplified form is 
Take a look at all 3 expressions: numbers, terms, and exponents.
4, 8, and 6 all have a GCF of 2.
y^5, y^3, and y^2 have a GCF of y^2.
Therefore, the GCF is 2y^2. Removing it gets you:
2y^2(2y^3 + 4y - 3)
Step-by-step explanation:
4
Add all to get 32
Divide by the number of items which is 8
answer =4
Answer:
9
Step-by-step explanation:
Answer: the addition of xy would make it a polynomial because it cannot simplify and the equation would have 3 different set of numbers that could not combine.
