simplify the expression and combine like terms.

2(x+1)+8+4x

2(x+1) + 8 + 4x can be simplified and combined by performing the distribution of the 2 on the terms in the parentheses, and then combining the like terms.

First, distribute the 2:
2(x+1) = 2x + 2

Now, the expression becomes:
2x + 2 + 8 + 4x

Next, combine the like terms:
2x + 4x = 6x

The expression simplifies further to:
6x + 2 + 8

Finally, combine the constants:
2 + 8 = 10

The final simplified and combined expression is:
6x + 10
