guys, may I know your working for this question?

y=ax+b tu linear function Yang nj ikut pola je

f(1) = 4
f(2) = 7

So 7-4=3

So .. f(3) = 7+3

congrats to amni madiha...

remember not all linear functions are arithemic sequences, but all arithemic sequences are linear functions..

congrats to Nisha also...👍🏽👍🏽👍🏽

Answer

haha, a very nice question...

congrats to Aireez

btw JEE advanced is one of the most toughest exams for undergraduate students..

Kepada batch 08 yang still ada dalam channel ni, mintak semua untuk bawa bertenang dan ada perasaan redha dengan keputusan spm anda. Saya doa dan pasti anda semua calon spm 2025 akan dapat straight A!! Amin🤲❤️

Kepada batch 09 juga, good luck for your upcoming exams, especially spm 2026. Be ready with every subject, conquer the chapter, jangan belajar last minit, dengar cakap cikgu dan jangan skip sekolah/kelas tambahan

Let x=length of the rectangle
h = height of the rectangle

Black line = h/tan(60°) = (h√3)/3

Using Pythagoras' Theorem,
[(h√3)/3 + x]² + h² = 36
h²/3 + (2xh√3)/3 + x² + h² - 36 = 0
h²(4/3) + [(2x√3)/3]h + (x²-36) = 0
h = [-(2x√3)/3 + √[(4x²/3)-(16/3)(x²-36)]]/(8/3)
h = [-x√3 + 3√(48-x²)]/4

Area of the rectangle, A = xh = x([-x√3 + 3√(48-x²)]/4)

dA/dx = (72-3x²-x√(144-3x²))/(2√(48-x²))

At Maximum, dA/dx = 0
(72-3x²-x√(144-3x²))/(2√(48-x²)) = 0
72-3x²-x√(144-3x²) = 0
=> x=-6 or x=2√3

Max A = 6√3
