A ∩ B = {3, 6, 9, 12} ∩ {2, 4, 6, 8, 10, 12}
= {6, 12}
If you would like to expand the expression 7 * (9 * x - 2), you can do this using the following steps:
7 * (9 * x - 2) = 7 * 9 * x - 7 * 2 = 63 * x - 14
The correct result would be 63 * x - 14.
<span>There were 12 wins. If they played 35 games, 12 were won and 14 were drawn, you just subtract them from 35 and you get 9. The team lost 9 games.</span>
