Verified Answer :

16x + \(12y^{2}\) + 4a + 12x

First, gather the like terms. / Your problem should look like: (16x + 12x) + \(12y^{2}\) + 4a
Second, simplify. / Your problem should look like: 28x + \(12y^{2}\) + 4a

Answer: A) 28x + \(12y^{2}\) + 4a

TSO

Add like terms

16x + 12x = 28x

16x + 12y^2 + 4a + 12x = 28x + 12y^2 + 4a

Your answer is A.
