Shannon is incorrect because the first expression is equal to 2 and the second expression is equal to 12.
Those expressions who might look different but their simplified forms are same expressions are called equivalent expressions.
To find out whether she is correct or not, we must get rid of the parentheses.
2 (3a - 2) + 4a
2 × 3a - 2 × 2 + 4a
6a - 4 + 4a
10a - 4
Since Shannon says 2(3a-2) + 4a and 10a-2 are equivalent, but when we work out the parentheses we can see a different outcome.
Therefore, Shannon is incorrect.
