Answer: 18+8b
Explanation:
To solve this expression, we need to follow the order of operations, which is:
Parentheses
Exponents
Multiplication and Division
Addition and Subtraction
First, we need to simplify the expression inside the parentheses by multiplying 2/3 by 12b and 15. We get:
8+2/3(12b+15)
8+2/3×12b+2/3×15
Next, we need to perform the multiplication and division operations from left to right. We get:
8+8b+10
Finally, we need to perform the addition and subtraction operations from left to right. We get:
18+8b
This is the simplest form of the expression. We cannot simplify it further unless we know the value of b.
