<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.

To factor a polynomial we need to find 2 numbers that add up to -15 and multiply into -54.
(-x -18)(x +3) Will be your answer.
Answer:
It's the first one because 5 x 3 = 15 and 10 x 3 = 30 and 15 x 3 = 45 and so on..
Step-by-step explanation:
It would be A. 12 is the highest common factor, 24-12 is 12 and 36-12 is 18
