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
 (4x + 1)

Answer:
Step-by-step explanation:
An equation contains a sign equality (=) between two expressions.
And an expression is a simple algebraic statement.
By these definitions,

          x = 2x + 5                            21x - 13 + 11x
           -3.7x - 13
                           -3.7x - 13  
          3x + 1 = -2.1
