1. volume balok adalah 1.620 cm³. jika panjang 15 cm,lebar 13 cm.maka berapakah tinggi nya?
f(x) = 4x + 2
f(a) = 18
a?
Nomor 1
Diketahui:
- V = 1.620 cm³
- p = 15 cm
- l = 12 cm
Ditanya:
- tinggi (t)
Penyelesaian:
- V = p × l × t
- t = V/(p × l)
- t = 1.620/(15 × 12)
- t = 1.620/180
- t = 9 cm

Nomor 2
f(x) = 4x + 2
f(a) = 4a + 2
18 = 4a + 2
4a = 18 - 2
4a = 16
a = 16/4
a = 4
SOAL 1
T Balok = Volume ÷ (P × L)
T Balok = 1.620 ÷ (15 × 12)
T Balok = 1.620 ÷ 190
T Balok = 9 cm
SOAL 2
f(x) = 4x + 2
f(a) = 4a + 2
18 = 4a + 2
-4a = -18 + 2
-4a = -16
a = -16 ÷ (-4)
a = -16 × (-1/4)
a = -16/-4
a = 4
