Q. 50+f(x) = 4x × 3 + 12x f(6) = …._____________​

Penjelasan dengan langkah-langkah:

f(x) = 4x × 3 + 12x

f(6) = 4(6) × 3 + 12(6)

f(6) = 24 × 3 + 72

f(6) = 72 + 72

f(6) = 144

f(x) = 4x × 3 + 12x

f(6) = 4(6) × 3 + 12(6)

f(6) = 24 × 3 + 12(6)

f(6) = 24 × 3 + 72

f(6) = 72 + 72

f(6) = 144

__

f(x) = 4x × 3 + 12x

f(6) = … 144
