To solve these equations we must make them equal to eachother. This gives us x²+4x+6=x+4, we must then subtract the 'x+4' fro...

We know that Amy bought 7 tickets for £24.50. This means to find out the price for each ticket, we divide the price for 7 tickets by 7: price per ticket = (24.50/7) = £3.50 Now we can find the total numbe...

To answer this question we need to combine like terms so that we do not have multiple x's. Knowing the order of operations is key here. First, we must multiple the coefficients outside the parentheses wit...

To find the turning points we need to find when the differential of the equations with respect to x is equal to 0. (dy/dx = 3x² - 12 = 0) From this we find that the turning points happ...

To solve such equations we take advantage of log lawes to simplify the problem .

E.g

ln[sqrt(1-x²)] = ln[(1-x²)^1/2] = 1/2ln[1-x²]

After sim...
