Question

Mă poate ajuta cineva??Vă rog frumos ​

Answer 1

Răspuns:

notăm a,b,c,d

a=nr par

b=a+2

c=a+2+2

d=a+2+2+2

a/---------/

b/--------/__2_/

c/-------/__2_/__2_/

d/------/_2__/_2__/__2_/

suma lor:412

412-2-2-2-2-2-2=400(suma nr in mod egal)

1+1+1+1=4(segmente egale)

400÷4=100(Un segment)

100×1=100(A)

100+2=102(B)

100+2+2=104(C)

100+2+2+2=106(D)

Răspuns: a=100

b=102

c=104

d=106

Sper ca te-am ajutat!
