If (x - 2) is a factor of 2x³ + x² - 3 then for the value of x = 2 the polynominal is equal zero.
Substitute:
2 · 2³ + 2² - 3 = 2 · 8 + 4 - 3 = 16 + 4 - 3 = 17 ≠ 0
Answer: B) (x - 2) is not a factor.
        
             
        
        
        
Answer:
10 boys
Step-by-step explanation:
6:2 simplfies to 3:1 30 / 3 = 10
30:10 simplfies down to 6:2
 
        
                    
             
        
        
        
Answer: the product is = 33+4i 
Step-by-step explanation: 
21+4i-12i^2 
21+4i-12(-1) i^2=-1
21+4i+12
your answer would be 33+4i .
 
        
             
        
        
        
Yes, both angles are acute because all complementary angles are acute.
