1. | GCSE Higher |
The diagram below is a sketch of \(y = f(x)\) where \(f(x)\) is a quadratic function.
The graph intersects the x-axis where \(x=-2\) and \(x = 0.5\).
Which of the following is the solution of \(f(x) \le 0\) ?
2. | GCSE Higher |
The volume of the larger red cube is 386cm3 greater than the volume of the smaller blue cube.
The lengths of the edges of the blue cube can be expressed as \(x\) cm.
The lengths of the edges of the red cube can be expressed as \(x+2\) cm.
(a) Show that \( x^2 + 2x - 63 = 0 \).
(b) Find the volume of the blue cube.
3. | IGCSE Extended |
(a) Show that the equation \(\frac{3}{x+1}+\frac{3x-9}{2}=1\) can be simplified to \(3x^2-8x-5=0\).
(b) Solve the equation \(3x^2-8x-5=0\) showing all of your working and giving answers to three significant figures.
(c) The total surface area of a cone with radius \(x\) and slant height \(8x\) is equal to the area of a circle with radius r. Show that \(r = 3x\).
[The curved surface area, \(A\), of a cone with radius \(r\) and slant height \(l\) is \(A=\pi rl\).]
4. | IB Studies |
A red rug has a width of \(x-3\) cm and a length of \(4x\) cm.
(a) Write down an ex
The area of the rug is 3240 cm2.
(b) Calculate the value of \(x\).
(c) Hence, write down the value of the length and of the width of the rug in centimetres.
5. | GCSE Higher |
In the diagram below, which is not drawn to scale, all dimensions are in centimetres and all angles are multiples of 90o. If the shaded area is 698cm2, work out the value of \(x\).
6. | GCSE Higher |
Given that:
$$ x^2 : (5x + 3) = 1 : 3 $$find the possible values of \(x\).
7. | GCSE Higher |
The area of triangle ABC (not drawn to scale) is
$$ \frac{35 \sqrt{3}}{4} m^2$$If AB = \(x+2\) metres and AC = \(2x+1 \) metres, find the value of \(x\).
If you would like space on the right of the question to write out the solution try this Thinning Feature. It will collapse the text into the left half of your screen but large diagrams will remain unchanged.
