Answer 1

Resposta:

Explicação passo a passo:

a) =(28+12) . (15+5)

=40 . 20

=800

b) = (28+48) . (15+15)

= 76 . 30

= 2280

c) = 4 . 12 . 3 . 10

= 48 . 3 . 10

= 144 . 10

= 1440    

d) = 4 . 7 + (36.5+5)

= 4. 7+(180+5)

= 4.7+185

= 28+185

= 213

a) 12+8+20=580 reais

20+20=580 reais

40 = 580 reais

b) 2.(20) =40 reais

40=40 reais

c)2.(20) =20 reais

40= 20 reais

d) 12+8+20=38 reais

20+20=38 reais

40=38 reais

25+8-2.3+9=

25+8-6+9=

33-6+9=
