Hello : 
<span>x^3-3x^2+2x=0
x(x²-3x+2) = 0
x(x-1)(x-2) = 0
x = 0 or x-1 = 0 or x-2= 0 
x = 0 or x = 1 or x = 2

elena55 [62]

Answer:

Displacement = 219.66 km

Displacement is the shortest length between the initial and final position.

Thus, the displacement can be calculate if we measure the starting point and final point of the Car drive. It is the straight line joining both the point.

Thus, Displacement = \sqrt{(215)^2+(45)^2} =219.66 \ km

fomenos

Answer:

\frac{3}{4}x + \frac{1}{2} = One-half more than three-fourths of a number

\frac{3}{4}-\frac{1}{2}x = Three-fourths minus one-half of a number

\frac{3}{4}-(x+\frac{1}{2}) = three-fourths minus the sum of a number and one-half

Step-by-step explanation:

Suppose x be an unknown number.

∵ 3/4th of a number = \frac{3}{4}x

\frac{3}{4}x + \frac{1}{2} = One-half more than three-fourths of a number

Now, half of a number = \frac{1}{2}x

\frac{3}{4}-\frac{1}{2}x = Three-fourths minus one-half of a number

Sum of a number and one-half = x+\frac{1}{2}

\frac{3}{4}-(x+\frac{1}{2}) = three-fourths minus the sum of a number and one-half
