Answer:
x^3(x-4)
Step-by-step explanation:
x^4-4x^3
x^3(x-4)
Knowing the fact:
1 km = 1000m
1 m = 100cm
We can calculate:
0.25 km = 0.25 * 1000m = 250m = 250 * 100cm = 25 000cm
It's 14 3/10 as a mixed number.
K, so, lets add them up
1+2=3
1+2+3=6
1+2+3+4=10
1+2+3+4+5=15
1+2+3+4+5+6=21
1+2+3+4+5+6+7=28
etc
basically
all numbers 'x' such that
x=

and n is the set of all natural numbers
