Hey there!
Guide
• 2 Negatives = [Positive]
• 1 positive & 1 negative = [Negative]
• 2 positives = [Positive]
• 1 negative & 1 positive = [Negative]
° So, this means that your answer most likely will equal a NEGATIVE number because you have 1 NEGATIVE (-3) number and 1 POSITIVE (“c” or 4.2) number.
-3c
= -3(4.2)
= -12.6
Therefore, your answer is: -12.6
Good luck on your assignment and enjoy your day!
