Let's solve the given expression step by step.

The expression is:

$(5)(3 - 1) + 4$

Step 1: Simplify the expression inside the parentheses

$3 - 1 = 2$

Now the expression becomes: $(5)(2) + 4$

Step 2: Multiply

$5 \times 2 = 10$

Now the expression is: $10 + 4$

Step 3: Add

$10 + 4 = 14$

Final Answer: A) 14

Would you like more details on this process, or do you have any questions?

Here are 5 related questions:

1. What happens if you change the operation inside the parentheses to subtraction?
2. How would the expression change if you added a division?
3. What if the value outside the parentheses was negative, e.g., $(-5)$?
4. Can this type of problem be extended to involve fractions?
5. How would the answer change if the value inside the parentheses was squared?

Tip: Always remember to follow the order of operations (PEMDAS: Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).
