The correct answers are D) 10x−14 and F) 2(5x−7) because they are equivalent to the simplified version of the given expression 3(2x−4)+4x−2.
D) 10x−14 This is already simplified and is exactly the same as our simplified expression from the given one. Therefore, it is equivalent.
F) 2(5x−7) Distribute the 2: 2(5x−7) becomes 10x−14, which is equivalent to our simplified expression.
