Answer:
7x + 5.6z
Step-by-step explanation:
To simplify any expression we use PEMDA ( order of operation)
Parenthesis
Exponents
Multiplication and division
Addition and subtraction
7x + (5.6) z
Here we have 5.6 inside the parenthesis
We multiply 5.6 with z
so it becomes 5.6z
7x + 5.6 z
Both terms 7x and 5.6z have different variable so they are not like terms
We cannot combine unlike terms, so we leave as it is
7x + 5.6z
