Answer:
B.  4x + 1
Step-by-step explanation:
4x^2 + 21x + 5 
= (4x + 1)(x + 5)
Factors of this trinomial are (4x + 1) and (x + 5)
Answer

Answer:
9
Step-by-step explanation:
a²+b
Substituting values,
=> (-2)^2+5
=> 4 + 5
=> 9
 
        
                    
             
        
        
        
2 + 4(3+2x) = 3x + 8
2 + 12 + 8x = 3x + 8
14 - 8 = 3x - 8x
6 = -5x
x = -6/5
