Answer:
A) 2x³+11x²+8x-16
Step-by-step explanation:
When you multiply s(x) by t(x) you get something like this:

 
        
                    
             
        
        
        
Step 1 ) Separate the 4 and x.

↓

Step 2 ) Simplify the square root of 4.

↓

Step 3 ) Simplify.

↓

This is now in its simplest form, so the final answer is...

or it could be...

Either one is correct. Only difference is one is in simplest form and one isn't.

Answer:
The 95% confidence interval of the mean time it took a person to find their dream home is between 5.64 months and 6.16 months.
Step-by-step explanation:
We have that to find our  level, that is the subtraction of 1 by the confidence interval divided by 2. So:
 level, that is the subtraction of 1 by the confidence interval divided by 2. So:

Now, we have to find z in the Ztable as such z has a pvalue of  .
.
So it is z with a pvalue of  , so
, so 
Now, find the margin of error M as such

In which  is the standard deviation of the population and n is the size of the sample.
 is the standard deviation of the population and n is the size of the sample.

The lower end of the interval is the sample mean subtracted by M. So it is 5.9 - 0.26 = 5.64 months
The upper end of the interval is the sample mean added to M. So it is 5.9 + 0.26 = 6.16 months.
The 95% confidence interval of the mean time it took a person to find their dream home is between 5.64 months and 6.16 months.
 
        
             
        
        
        
It can be factored. 
We need two numbers that multiply to -12 and add to -4, so are two terms would be -6 and 2.
(x - 6) (x + 2) = 0 
x = 6 
x = -2
        
                    
             
        
        
        
Answer:
Less
Step-by-step explanation:
56 is multiplied by 19/20 which is obviously less than one
