Answer:
- 36
Step-by-step explanation:
First evaluate g(18), then substitute the value obtained into h(x), then substitute the value obtained here into f(x).
g(18) = = = 6, then
h(6) = | 4(6) | - 12 = | 24 | - 12 = 24 - 12 = 12, then
f(12) = - 3(12) = - 36
The triangle has height 4.6 mm and its base has length 3.4 mm, so its area is
1/2 • 4.6 mm • 3.4 mm = 7.82 mm²
