Randy is checking to determine if the expressions 2x+2+4x and 2(3x+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 2x+2+4x=14. What is the value of the second expression when x is equal to 2 , and are the two expressions equivalent?
Answer
A
The value of the second expression is 14 , so the expressions are equivalent.
B
The value of the second expression is 20 , so the expressions are equivalent.
C
The value of the second expression is 12 , so the expressions are not equivalent.
D
The value of the second expression is 7 , so the expressions are not equivalent.
