Step-by-step explanation:
x³ - 4x² + x - 4
= x²(x - 4) + (x - 4)
= (x² + 1)(x - 4).
Since the quadratic factor (x² + 1) is irreducible any further, this is our answer.
X= 20 y= 100

Answer:
x = 2
Step-by-step explanation:
Step 1: Subtract 2x from both sides.
4x+14−2x=2x+18−2x
2x+14=18
Step 2: Subtract 14 from both sides.
2x+14−14=18−14
2x=4
Step 3: Divide both sides by 2.
2x

Answer:
18
Step-by-step explanation:
x + (x + 1) + (x + 2) = 57
x + x + 1 + x + 2 = 57
x + x + x + 1 + 2 = 57
3x + 3 = 57
3x = 57 - 3
3x = 54
x = 54/3
x = 18
$ 40 ..... 100 %
$ 28 ..... x %

The % of change is 70 %.
This is equivalent with:
- the final price ($ 28) is 70 % from the initial price ($ 40)
- the initial price ($ 40) was reduced with 30% giving the new price as:
