Answer:
option 4
Step-by-step explanation:
(f*g)(x) =(x² + x+ 1)*(x² - x -1)
            = x²*(x² - x -1)   + x(x² - x -1) + 1*( x² - x -1)
             = x²*x² - x²*x -x²*1   + x*x² - x*x -x*1 + x² - x -1
             = x⁴ - x³ - x² +x³ - x²  - x  + x² - x -1
            = x⁴  - x³ + x³  - x² - x² + x² - x - x - 1
        = x⁴ - x² - 2x - 1
 
        
                    
             
        
        
        
9/200. divide 45 and 1000 both by 5 to reduce it.
        
             
        
        
        
Angles are the space between intersecting lines, and they are measured in degrees or radians
The measure of angle ABC is y + x
<h3>How to determine angle ABC</h3>
The given parameters are:
ABD=y,
DBC=x,
EFH=y, 
EFG=x
PQS = SQR = x
To determine the measure of angle ABC, we make use of angle ABD and angle DBC
Note that angle ABD and angle DBC have common vertices at points B and D
So, we have:
ABC = ABD + DBC
Substitute known values
ABC = y + x
Hence, the measure of angle ABC is y + x

Answer:
29 Minutes
Step-by-step explanation:
The original speed is given in miles per hour (like a car), but the answer is asking for miles per minute, so we must convert the speed into miles per minute first. To do this, we set up this equation:  which equals
 which equals   . We can then divide the desired number of miles by the speed in miles per minute. Here is the eqaution for this
. We can then divide the desired number of miles by the speed in miles per minute. Here is the eqaution for this  . The miles cancel and you are just left with 29.1 minutes after you divide 4.9 by 0.168333333. Hope this helps!
. The miles cancel and you are just left with 29.1 minutes after you divide 4.9 by 0.168333333. Hope this helps!
