СРОЧНООО ПОМОГИТЕ С РЕШЕНИЕМ а)-48•25+28•25 б)-138+24-(29+38)

Answer 1

А)-48×25+28×25=25(-48+28)=25×(-20)=-500
б)-138+24-(29+38)=-138+24-67=-181

Answer 2

Calculating the expressions step-by-step:

a) -48•25 + 28•25 -48•25 = -1200 28•25 = 700 -1200 + 700 = -500

b) 138 + 24 - (29 + 38) 29 + 38 = 67 138 + 24 = 162 162 - 67 = 95

The answers are: a) -500 b) 95
