[{"id":12108,"question":"Quelle est la solution de l'équation 3x + 5 = 20 ?","option_a":"x = 5","option_b":"x = 15","option_c":"x = 10","option_d":"x = 4","option_e":"","option_f":"","bonne_reponse":"A","explication":"Pour résoudre 3x + 5 = 20, soustrayez 5 des deux côtés : 3x = 15, puis divisez par 3 : x = 5.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":12109,"question":"La fonction f(x) = 2x² + 3x - 5 est-elle une fonction affine ?","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"B","explication":"Une fonction affine s'écrit sous la forme f(x) = ax + b. Ici, le terme x² indique qu'il s'agit d'une fonction du second degré.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":12110,"question":"Quel est le résultat de (2 + 3) × 4 ?","option_a":"20","option_b":"14","option_c":"9","option_d":"10","option_e":"","option_f":"","bonne_reponse":"A","explication":"D'abord, calculez la parenthèse : 2 + 3 = 5. Puis multipliez par 4 : 5 × 4 = 20.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":12111,"question":"Dans un triangle rectangle, le carré de l'hypoténuse est égal à la somme des carrés des deux autres côtés. Vrai ou faux ?","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"A","explication":"C'est le théorème de Pythagore, une propriété fondamentale des triangles rectangles.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":12112,"question":"Quelle est la dérivée de la fonction f(x) = 4x³ ?","option_a":"f'(x) = 12x²","option_b":"f'(x) = 4x²","option_c":"f'(x) = 3x²","option_d":"f'(x) = 12x³","option_e":"","option_f":"","bonne_reponse":"A","explication":"La dérivée de x^n est n×x^(n-1). Ici, 3 × 4x² = 12x².","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":12113,"question":"Un angle de 90 degrés est-il un angle plat ?","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"B","explication":"Un angle plat mesure 180 degrés. Un angle de 90 degrés est un angle droit.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":12114,"question":"Quelle est la solution de l'inéquation 2x - 7 \u003E 3 ?","option_a":"x \u003E 5","option_b":"x \u003E 10","option_c":"x \u003C 5","option_d":"x \u003C 10","option_e":"","option_f":"","bonne_reponse":"A","explication":"Ajoutez 7 des deux côtés : 2x \u003E 10, puis divisez par 2 : x \u003E 5.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":12115,"question":"La médiane d'un triangle passe-t-elle par le milieu de chaque côté ?","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"A","explication":"La médiane d'un triangle est une droite qui joint un sommet au milieu du côté opposé.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":12116,"question":"Quel est le PGCD de 24 et 36 ?","option_a":"6","option_b":"12","option_c":"8","option_d":"18","option_e":"","option_f":"","bonne_reponse":"B","explication":"Les diviseurs de 24 sont 1, 2, 3, 4, 6, 8, 12, 24. Ceux de 36 sont 1, 2, 3, 4, 6, 9, 12, 18, 36. Le plus grand commun est 12.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":12117,"question":"La probabilité d'un événement impossible est-elle égale à 0 ?","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"A","explication":"Un événement impossible ne peut pas se produire, donc sa probabilité est 0.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0}]
