Answer:
The coefficient is 
Step-by-step explanation:
The given sum is

We can choose to add only the coeffients of
or simplify the whole sum.

We collect the LCM for the
terms;

This will give us;

Which is the same as

The coefficient is 
F(x) = -3(x + 2)(x - 5)^3 > 0
(x + 2)(x - 5) > 0
x + 2 > 0 or x - 5 < 0
x > -2 or x < 5
-2 < x < 5
Therefore, the stated interval is false.
Answer: 50%
Step-by-step explanation:
In 2010 the percentage of fatal accidents was 16%.
This is 34% less than it was in 2000 because the text says that the 2010 percentage was 16% after being reduced by 34% from 2010.
The percentage of fatal accidents in 2000 is therefore:
= 2010 fatal percentage + Percentage reduced from 2000
= 16% + 34%
= 50%
