Randy is checking to determine if the expressions 2 x + 2 + 4 x and 2 (3 x + 1) are equivalent. When x = 3, he correctly finds that both expressions have a value of 20. When x = 2, he correctly evaluates the first expression to find that 2 x + 2 + 4 x = 14. What is the value of the second expression when x = 2, and are the two expressions equivalent?
The value of the second expression is 7, so the expressions are not equivalent.
The value of the second expression is 12, so the expressions are not equivalent.
The value of the second expression is 14, so the expressions are equivalent.
The value of the second expression is 20, so the expressions are equivalent.
