"A container built to hold statures is based on a rectangular cuboid"
The volume in cubic meters is given by the formula V=x^3 + 6x^2 + 8x
a) Show that the sides have lengths x,x+2 and x+4 meters.
b)An expresssion for the surface area of the container is 6x^2 + 24x +16
If the surface are of the container is 142m^2, what is the volume?
"A rectangular garden has a perimeter of 22m and an area of 21.84m^2. The width of the garden is x meters and the length is y meters.
a) Write two equations for this situation in terms of x and y
b) Solve the equations simultaneously and state the dimensions of the garden
Any help would be great!
