The answer would be -2x^4y^6. first make a fraction with it then divide the coefficients and subtract the exponents, the difference of the exponents will go where the bigger number was.
The correct answer is D to the question that you are asking
Answer:
In two similar geometric figures, the ratio of their corresponding sides is called the scale factor.
To find the scale factor,we need to follow some rules:
locate two corresponding sides, one on each figure.
Write the ratio of one length to the other to find the scale factor from one figure to the other
This looks like: 
To solve this problem, you'll want to use the AC method to factor x^2+7x-30.
After factoring your expression will look like this:

Cancel out the x+10 because they are common factors, so you are just left with the simple x-3.
Answer is:
x - 3
Answer:
f(g (x))= 32x-18
g (f (x))=32x2+42
Step-by-step explanation:
f (g (x))= 4 (8x-6)+6
32x-24-6
32x-18
g (f (x))= 8(4x2+6)-6
32x2+48-6
32x2+42
