1. The dimensions of a box are 3 cm 5 cm 7 cm. The width, length, and height of the box must be increased by the same amount x in order for the box to have a volume of 693 cm cubed. Determine the value of x that will produce a box with a volume of 693 cm3.

2. The specifications for a storage container state that the length is 1 metre more than triple the width and the height is 5 metres less than double the width. Find the range of possible dimensions for a volume of at least 8436 m3 using the algebraic method.

4. Solve the following inequality algebraically. Explain your process.
