Which expression is equivalent to 0.2n + 2n + 4?

The original expression we have is: 0.2n + 2n + 4

In this expression we have two terms having the variable "n", this means that we can add the coefficients in these two terms together.

Therefore, the expression would now be:

n (0.2+2) + 4 which is equivalent to:

2.2n + 4

We can take the two as a common factor from both terms, the resulting expression would now be:

2 (1.1n+2)

2.2+4 is your answer
