​

Answer 1

Răspuns:

Explicație pas cu pas:

4×7+4×11+4×22 = 4 x (7 + 11 + 22) = 4 x 40 = 160

5×30+5×25+5×15 = 5 x (30 + 25 + 15) = 5 x 70 = 350

Answer 2

4 × 7 + 4 × 11 + 4 × 22 =

4 × ( 7 + 11 + 22 ) =

4 × ( 18 + 22 ) =

4 × 40 = 160

5 × 30 + 5 × 25 + 5 × 15 =

5 × ( 30 + 25 + 15 ) =

5 × ( 55 + 15 ) =

5 × 70 = 350
