BonsoirA = x² - 2 x + 2
pour x = 0 , A = 2
pour x = 1 , A = 1 - 2 + 2 = 1
pour x = 3, A = 9 - 6 + 2 = 5
pour x = - 1, A = 1 + 2 + 2 = 5
pour x = - 2 , a = 4 + 4 + 2 = 10
pour x = - 3 , A = 9 + 6 + 2= 17
a) c² donc 7² = 49
b) L x l = 8 x 2.5 = 20
c) (B x h)/2 = 6 x 7 = 42 : 2 = 21
d) πR² = π7² = π49
e) πR² = π10² = π100
Cylindre = πR² x h
π1²x 5 = π5
