Answer:
x = 0 , 2/3
Step-by-step explanation:
3x^3-x^2=x^2
3x^3-2x^2=0
x^2(3x-2)=0
Now split into two equations:
1)
x^2=0
x=0
2)
3x-2=0
3x=2
x=2/3
1 meter = 100 centimeters

Lets plug in the values:
First, divide both sides by 800.
Multiply x by 1

Now, we multiply .08 by 100 to get our interest rate:
(.08)100 = 8
The interest rate is 8%
