Question

1=(2,5+1,5).(2,5+1)=
2=(2,5+1).(2,5+0,5)=
3=(1,5+1).(1,5+0,5)=
4=(3+2).(3+1)=
5=(3+2).(3+2,5)=

ajuda

Answer 1

(2.5 + 1.5).(2.5 + 1) = (4)(3.5) = 14
(2,5 + 1).(2,5 + 0,5) = (3.5)(3) = 10.5
(1,5 + 1).(1,5 + 0,5) = (2.5)(2) = 5
(3 + 2).(3 + 1) = (5)(4) = 20
(3 + 2).(3 + 2,5) = (5)(5.5) = 27.5
