Answer:

hello :

expressions are equivalent to 4b :

b )    3b +b = 4b

c)    2(2b) = 4b

but :  a) is not equivalent to 4b  

because :   b+2 (b+2b) = b + 2b +4b = 7b

Answer 2

Answer:

They are b and c.

Step-by-step explanation:

Let's simplify each expression:

a. b+2 (b+2b)

= b + 2b + 4b = 7b.

b.  3b + b = 4b.

c. 2(2b) = 2 * 2b = 4b.
