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
 
        
                    
             
        
        
        
Then 1 white, then 3 blue then 1 white
        
             
        
        
        
Answer:
5
Step-by-step explanation:
6a = (a*-3) + 45
then:
6a = -3a + 45
6a + 3a = 45
9a = 45
a = 45/9
a = 5
Check:
6*5 = (5*-3) + 45
30 = -15 + 45
