9+3x^2
It's technically already in simplest form, except you usually put x first
=3x^2+9
Firts, Let

be the repeated decimal that we are trying to convert , so

equation (1)
Next, lets find how many digits are repeating:
It is pretty cleat that 90 is repeating, and 90 has two digits. So we are going to multiply our equation by 100 to move the decimal point two places:

(2)
Subtract equation (1) from equation (2):


Solve for


We can conclude that 10.9090909091... expressed as a rational number, i<span>n the form pq where p and q are positive integers with no common factors, is </span>

.
The answer would be 360 :) do you have to show working?
What a clever sneaky little problem !
There can only be two of them: 1221 and 2112 .
Step-by-step explanation:
Since this circle is partial we will divide the area of the whole circle by 2
the area of a circle is expressed by
so insert 14 for the radius.


divide the area by 2

Hope that helps :)
