Answer:
Step-by-step explanation:
No she is not correct because 2 times 3a is 6a and -2 times 2 is -4. And then 6a plus 4a is 10a. So therefore the equation would be 10a -4 which is not equivalent to 10a -2. Hope this helps you
No, she's not correct. The first expression is equal to 2 and the second expression is equal to 12. So, it's NOT CORRECT.
