Answer 1

" Penyelesaian Soal"

f(x) = 5x + 5x² + 12x

f(5) = 5(5) + 5(5²) + 12(5)

f(5) = (5×5) + (5×(5×5) + (12×5)

f(5) = 25 + (5 × 25) + 60

f(5) = 25 + 125 + 60

f(5) = 150 + 60

f(5) = 210

Semoga bermanfaat..

Answer 2

f(x) = 5x + 5x² + 12x

f(5) = 5(5) + 5(5)² + 12(5)

f(5) = (5 × 5) + 5(5)² + 12(5)

f(5) = 25 + 5(5)² + 12(5)

f(5) = 25 + 5(5 × 5) + 12(5)

f(5) = 25 + 5(25) + 12(5)

f(5) = 25 + (5 × 25) + 12(5)

f(5) = 25 + 125 + 12(5)

f(5) = 25 + 125 + (12 × 5)

f(5) = (25 + 125) + 60

f(5) = 150 + 60

f(5) = 210

Kesimpulan hasilnya adalah : 210
