<em><u>Answer</u></em>:
a+a+a = 3a.
4b-b = 3b.
3x²+x² = 4x².
<u><em>explanation</em></u>
a+a+a = 3a.
4b-b = b(4 - 1) = b × 3 = 3b.
3x²+x² = x²(3 + 1) = x² × 4 = 4x².

Answer:
No, No, Yes, Yes.
Step-by-step explanation: 2 times -3 = -6. -6 times -4 = 24. 
So, with that said, the first one multiples out to -24.
The second multiplies out to again -24. 
12 times 2 = 24.
A negative and a negative multiply to become a positive, so -4 times -6 = 24.
