Answer:
d) 2x²(6x³ + 3x + 4)
Step-by-step explanation:
In order to factor the given polynomial, you need to find the greatest common factor of all three terms:

2x²(6x³ + 3x + 4)
B. I’m pretty sure. Since the arrow is pointing towards the S which is at the beginning.
Answer:
x = 7.5
Step-by-step explanation:
Since DF bisects ∠CDE then
∠EDF = ∠CDF, hence
8x = 4x + 30 ( subtract 4x from both sides )
4x = 30 ( divide both sides by 4 )
x = 7.5
