Wyrażenia algebraiczne Uzupełnij tabelkę: a | 3 | 4| |10 | b |4 | | 2 | |0 a-b | | | | | 5*(a+b) | | | | | 5*(a+b)-b | | | | |0 Błagam pomóżcieee!!!!!!!!!!!!!!!!!!!!!

a - b 1. 3 - 4 = -1 2. 4 - 2 = 2 3. 10 - 0 = 10 5(a+b) 1. 5 × 3 + 5 × 4 = 15 + 20 = 35 2. 5 × 4 + 5 × 2 = 20 + 10 = 30 3. 5 × 10 + 5 × 0 = 50 5(a+b)-b 1. 35 - 4 = 31 2. 30 - 2 = 28 3. 50 - 0 = 50 O to Ci chodziło?

a - b 3 - 4 = -1 4 - 2 = 2 10 - 0 = 10 5(a+b) 5 ×(3+4) = 35 5 ×(4+2)= 30 5 × (10+0) 50 5(a+b)-b 35 - 4 = 31 30 - 2 = 28 50 - 0 = 50
