Final answer:
The correct answer is option B: 2x(15x4). To find twice the product of 15 and 4, we multiply 15 and 4 first, and then multiply the product by 2. The final answer is 120.
Step-by-step explanation:
To find twice the product of 15 and 4, we multiply 15 and 4 first, and then multiply the product by 2.
The product of 15 and 4 is 60. Multiplying 60 by 2 gives us the final answer of 120.
The question asks for an expression that represents twice the product of 15 and 4. To find the product, you multiply 15 and 4, which is 15x4. Then, to find twice that product, you would multiply the result by 2, which is 2x(15x4). This matches option B. None of the other options correctly represent twice the product of 15 and 4. Option C, for instance, represents two times the sum of 15 and 4, which is a different operation.
