Раскройте скобки 3(8+b) 8(x-7) (8-m)*15 22(7x+4) 7(3m+9n-18p) (21a-15b+33c)*12

Question

Раскройте скобки
3(8+b)
8(x-7)
(8-m)*15
22(7x+4)
7(3m+9n-18p)
(21a-15b+33c)*12

Answer 1

3 (8+b)= 24+3b
8 (x-7)= 8x-56
(8-m)*15= 120-15m
22 (7x+4)= 154x+ 88
7 (3m+9n-18p)= 21m+63n-126p
(21a-15b+33c)*12= 154a-180b+396c
