Answer:
The largest factor that can be pulled out of that expression is 20x, giving you 20x(x² - 2x + 4)
Step-by-step explanation:
20x³ - 40x² + 80x
= 20x(x² - 2x + 4)

Yes, as one half or 1/2 is also 10/20. 11/20 is greater than half by a 10% margin.
That would be 20,30,40,50,60,70,80,90,100,110,120,130. 200,150,300,250
650 + 250 = so the answer would be 900.
