Given:
• Maggie's equation: ,-7 x (-12) = -84
• Carlos' equation: ,-7 x (-12) = 84
Let's determine who is right.
To determine let's simplify the expressions on the left.
Hence, we have:
[tex]-7\times(-12)=--84=84[/tex]Therefore, the correct equation is:
[tex]-7\times(-12)=84[/tex]Therefore, Carlos is right.
ANSWER:
Carlos
