Answer:
c
Step-by-step explanation:
Answer:
yx=8 and xy=20 so that is the correct answer
1.
The degree of this polynomial is 5, and because the prefix for 5 is "quin", the answer would be quintic.
2. -2x^2(-5x^2 + 4x^3)
We can use FOIL to simplify this.
10x^4 - 8x^5
Because standard form is decreasing by degree, we need to rearrange the binomial.
The answer is -8x^5 + 10x^4
9(x+3)=108
x+3=108/9=12
x=12-3=9
