Bonsoir,
DC: 7/5
CG + AD = 7/3
GF = 7/3
FE = 7/3
BE = 7/3
AB = 7/5
7/5 + 7/5 + 7/3+7/3+7/3+7/3
= 14/5 + 21/3
= 14/5 + +7
=14/5 + 35/5
= 49/5
bonjour
tu postes trop de devoirs, ça te jouera des tours !
7 /5 + 2/3 + 7/5 + 7/3 + 7/3 + 7/3 + 7/3 = 30/3 + 14/5 = 150/15 + 42/15
= 192/15 = 64/5
P = 64/5
( 2/3 x 7/5) + ( 7/3 )²
= 14/15 + 49/9
= 42/45 + 245/45
= 287/45
A = 287/45
