Answer:
C
Step-by-step explanation:
x(x2 + 5) – 9(x2 + 5)
= x³ + 5x - 9x² - 45
(try to expand one by one of the answer given)
They have the same slope, but different y-intercepts, making them parallel.
B. 4
3n - (2 + n)
3(4) - (2 + 4)
12-6
=6
2x³+18x²<span>-18x-162 =
2(</span>x³+9x²-9x-81)=
2(x²(x+9)-9(x+9))=
2(x²-9)(x+9)=
2(x+3)(x-3)(x+9)
Answer: k=3
