Answer:
(a) check the explanation
(b) the possible values of b is 6i or -29
Explanation:
Given function;
16x⁴ - 4x³– 4b²x² + 7bx + 18
(a)
factor of the given function = 2x + b
then, 2x + b = 0
x = -b/2
substitute the value of b into the given function;
16x⁴ - 4x³– 4b²x² + 7bx + 18
(b)
b³ - 7b² + 36 = 0
b²(b - 7) + 36 = 0
b²(b - 7) = -36
b² = -36 or b - 7 = -36
b = √(-36) or b = -36 + 7
b = √(-1) x √(36) or b = -29
b = 6i or -29

ABS system increases the ability to maintain traction
<u>Explanation:</u>
- Traction is the grip of the tyre on the rail or road to avoid skidding of the vehicle.
- ABS system is the "anti-lock braking system" used on land vehicles to prevent skidding of the vehicles. When sudden breaks are applied, there is a possibility for the vehicle to get locked up. This system allows the vehicle by preventing the wheels from locking.

Answer:
Democracy is a form of government in which the rulers are elected by the people. One chief factor common to all democracies is that the government is chosen by the people. It also helps students to demarcate between democratic and non-democratic governments. From the non-democratic government, take the example of Myanmar, where rulers were not elected by the people. Those who were in charge of the army of the country took over as rulers and people had no say in this decision. Dictators like Pinochet (Chile) are not elected by the people. This also applies to monarchies.
