Simplifying the Expression (2 + b) ⋅ 5 + 4(3b - 1)
This article will guide you through simplifying the expression (2 + b) ⋅ 5 + 4(3b - 1) using the order of operations and the distributive property.
Understanding the Order of Operations
The order of operations, often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction), is crucial for simplifying mathematical expressions.
Applying the Distributive Property
First, we need to apply the distributive property to remove the parentheses:
- (2 + b) ⋅ 5: This becomes 10 + 5b
- 4(3b - 1): This becomes 12b - 4
Combining Like Terms
Now, our expression looks like this: 10 + 5b + 12b - 4
We can combine the terms with 'b' and the constant terms:
- 5b + 12b = 17b
- 10 - 4 = 6
Final Simplified Expression
The simplified expression is 17b + 6.
Therefore, (2 + b) ⋅ 5 + 4(3b - 1) is equivalent to 17b + 6.
