Thank you!
You're welcome.
To simplify the expression 5x + 4 + 2x + 5, you can combine like terms by adding or subtracting the coefficients of the variables with the same power.
First, group the terms that have the variable x:
5x + 2x
Combine the coefficients of x:
5x + 2x = 7x
Next, group the constant terms:
4 + 5
Combine the constant terms:
4 + 5 = 9
Therefore, the simplified expression is 7x + 9.
