First we should draw what the question tells us.Draws circle with square inside it
We want to find out some extra information about the circle based on what we have been told.
How can w...

First you must convert the diameter into cm from mm:19/10 = 1.9cmThen you must find the radius of the ring:radius = diameter/2 = 1.9/2 = 0.95 cmThen you can calculate the area:area = 2πr² = 2 x...

First, we simply label the two equations as 'Equation 1' and 'Equation 2' respectively. So we have: Equation 1: 2x + y = 18and Equation 2: x - y = 6. In simultaneous equations, there are two variables: x ...

x(x+1) - x(x-1)/(x-1)(x+1)x²+x-x²+x/(x-1)(x+1)2x/x²+x-x-12x/(x²-1)

13y - 5 = 9y + 27 First we must collect all similar terms together on either side of the equation: 13y - 9y = 27 + 5. As you can see, if a term is moved to the other side of the equation, the opposite sig...
