daca e tetraedru regulat inseamna ca are toate muchiile congurente=> fetele sunt triunghiuri echilaterale. tatraedrul are 4 fete=> A totala=4• A fata. A fata=L²√3:4=16√3 cm². A totala=64√3 cm². Sper ca te-am ajutat :)

Développer et réduire les expressions quand c'est possible :

A = 2×(a + 3)

B = (x - 4)×3x

C = 4y - 3y(1+3y)

D = (2 - y) × 5

E = 10 + 3 (x - 5)

F = (2y + 1)(3 - 4y)

H = - 2x (3x - 2)

I = 4a - (4 + 3a)

J = 4(5y - 3) - (10y + 1)(2y - 4)
