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)
