To calculate the perimeter (the length of the outside edge) of a square, you must add up the length of each side. Here, we have been given the area of the square. The area of a square is calculated by squ...

To be able to solve a quadratic, you must make it equal to zero. So the first thing you have to do is take away 5 from both sides. You could take away 6x^2-13x from each side, but it is much easier to kee...

The main three trigonometric functions are the tangent (tan), sine (sin) and cosine (cos) functions. The tangent, sine and cosine of an angle is defined in terms of the ratios of the length of sides of a ...

Firstly you could work out the x intercept by putting y=0 in to the function of the graph and then similarly find out the y intercept by putting x=0 into the function. After this you could find the turnin...

First, we start with what we do know and this should lead us to the answer with steps inbetween. So the amount of yellow sweets to start is (n-6) but we want to focus on the orange sweets. This question i...
