Mice are small and kilograms are for much larger objects. The other two measurements are for liquids.
10 + 6n = 4 - 4n
I'm just guessing but I'm pretty sure that's it.
Ok so we know that the distance around the circle (or circumference) is equal to the diameter times pi.
This means that

d being the diameter,
This means that:

= 12.00028271
= 12 m
So the diameter of the circle is 12 metres.
Hope this helped
<u>Given</u>:
The quadratic equation is 
We need to determine the solutions of the quadratic equation.
<u>Solution</u>:
Let us solve the equation to determine the value of x.
Adding both sides of the equation by 5x and 3, we get;

The solution of the equation can be determined using quadratic formula.
Thus, we get;



Thus, the two roots of the equation are
and 
Hence, the solutions of the equation are
and
