Question

dau coroana pls pls daca se poat pana la15:45

Answer 1

a) a*b+a*c = a(b+c) = 6*157=942

b) a*b-a*c = a(b-c) = 25*147= 3,675

c) a*b+a*c+a*d = a(b+c+d) = 14*59 = 826

Answer 2

a) a × b + a × c = a × ( b + c ) = 6 × 157 = 942

b) a × b - a × c = a × ( b - c ) = 25 × 147 = 3 675

c) a × b + a × c + a × d = a × ( b + c + d ) = 14 × 59 = 826

→ am aplicat proprietatea inmultirii de distributivitate, dand factor comun pe a;
