A 4x2 wheel drive refers to the setup of a driveline in a vehicle, typically in light trucks. It indicates that the vehicle has four tires, with two of them at most providing power.
Know MoreIn most light trucks, the back wheels provide the power while the front ones are used for steering. A 4x2 can also be used for 4x4 trucks with the front axle disengaged from the engine. The advantages of this setup are simplicity and durability. However, 4x2 vehicles perform worse in extreme terrain and may not have sufficient traction necessary to keep the vehicle from getting stuck in ice, snow or mud.

Full Answer >The weight of a 2-inch by 4-inch lumber board depends on its length and the type of wood from which it is made. A green-lumber 2-by-4 with a length of 8 feet weighs 13 pounds. A green-lumber 2-by-4 with a length of 12 feet weighs 20 pounds.
Full Answer >The expression (x^2 - 2x - 4) factors as (x + 1 - sqrt(5))*(x + 1 + sqrt(5)), where sqrt(5) is the square root of 5. This quadratic polynomial is factored by completing the square, a method in which a particular number is both added to and subtracted from the polynomial in order to factor the polynomial.
