Answer:
x = 2 is the solution of x^3 - x - 6
Step-by-step explanation:
(x^3) - x - 6 = 0
If x = 2,
--> (2^3) - 2 - 6
= 8 - 2 - 6 = 8 - 8 = 0.

Step-by-step explanation:
4)
28 in base 10
base 5=28*2=56
base 2=28*5=140
5)
7 in base 10
base 5=7*2=14
base 2=7*5=35
6)
100 in base 2
base 5=100*5/2=500/2=250
base 10=100*5=500
7)
10010 in base 2
base 5=10010*5/2=50050/2=25025
base 10=10010*5=50050
8)
10111 in base 2
base 5=10111*5/2=50555/2=25277.5
base 10=100*5=50555
Step-by-step explanation:

9/10-2/5= first you must get a common denominator
you don't have to change the first fraction but the second one 2/5 multiply the top and bottom number by 2
9/10- 4/10=5/10 is the answer but you can simplify because 5 divides into 10 so 5 goes into 5 1 time and 5 goes into 10 2 times
final answer is 1/2
