For this question, the main component of the equation we need o look at is (x+8)^2. We know that (x+8)^2 is the same as (x+8)(x+8). First we have to expand these brackets. For his I make small table to en...

First, we can draw a diagram to visualise the triangle and the elements of the question. Looking at this, we can see that we know the length of the hypotenuse (H) and we need to calculate the length of th...

First, work out 10% of 12000 as this is a much easier calculation. To do this, one "0" can be taken off the end of the number, to give 1200. Then, to work out 20%, we know that 10x2 = 20. So, 10...

x²+7x+6=0First identify factors of 66x1=63x2=6Then look at these pair and see if either of the can be added/subtracted from each other to give the value of 7. Therefore you would use 6+1=7These...

Firstly, we need to think of the equation of a line formula to figure out what information we have been given. y-y1 = m(x-x1) -> (x1, y1)This formula uses a point and a slope. We have been given a poin...
