Раскройте скобки: 4*(x-8) 8*(x+3) (7- x)*8 (4a-c)*12 9*(3a-7b+8c) (5x+8y-3k)*12

1) 4 * (x - 8) = 4 * х - 4 * 8 = 4 * х - 32;

2) 8 * (x + 3) = 8 * х + 8 * 3 = 8 * х + 24;

3) (7 - x) * 8 = 7 * 8 - 8 * х = 56 - 8 * х;

4) (4 * a - c) * 12 = 12 * 4 * а - 12 * с = 48 * а - 12 * с;

5) 9 * (3 * a - 7 * b + 8 * c) = 9 * 3 * a - 9 * 7 * b + 9 * 8 * c = 27 * a - 63 * b + 72 * c;

6) (5 * x + 8 * y - 3 * k) * 12 = 12 * 5 * x + 12 * 8 * y - 12 * 3 * k = 60 * х + 96 * у - 36 * k.
