Using the chain rule:If the parameter used is 't', differentiate each equation with respect to 't' so that you have answers for dy/dt, and dx/dt.From the chain rule it is known that: "dy/dx=dy/du * d...

first expand the brackets (3x-2)(x+1) to get 3x²-2x+3x-2, then we can simplify this to get 3x²+x-2.Then multiply this by x to get the final answer: 3x³+x²-2x.

Each banana cost 30p so the total price for bananas will be "number of bananas x 30". Here, bananas are called by the variable x so this number can be written as "30x" and will change ...
