Yes you are right it's C)
Notice that f(-2) = (-2)³ +2( - 2)² + 4(-2) + 8 =0
Then x³+2x²+4x+8 is divisible by (x+2)
Perform this division & you will get:
x³+2x²+4x+8 = (x+2)(x²+4)
The root of (x+2) is the value that render it nil, that is x=-2
The root of (x²+4) are imaginary (not real) because
x²+4 =0 ==> x² = -4 & x=√-4 or x= 2i (nor real).
Hope you understood the reasoning

Answer:
320 sq.feet

Answer: There are 60060 ways to do so.
Step-by-step explanation:
Since we have given that
Number of linden trees = 6
Number of white birch trees = 4
Number of bald cypress trees = 3
Total number of trees = 6 +4 +3 =13
So, Number of ways that the landscaper plant that trees are evenly spaced is given by
Hence, there are 60060 ways to do so.
