2. Выполни по образцу. 8. (30 + 7) = 8.30 + 8.7 = 296 6. (50 + 4) = 8.37 = 296 7.(20 + 8) = 5. (40 + 6)

5 • (40 + 6) = 5 • 40 + 5 • 6 = 230

6 • (50 + 4) = 6 • 50 + 6 • 4 = 324

7 • (20 + 8) = 7 • 20 + 7 • 8 = 196

5×(40+6)=5×40+5×6=230

5×46 =230

6×(50+4)=6×50+6×4=324

6×54=324

7×(20+8)=7×20+7×8=196

7×28=196
