Problem solving:

i have square paving tiles in two different colours. i want you to design for me a paved area that is made up of a rectangle in one colour surrounded by a border in the other colour. i want however to use exactly the same number of pavers of each colour and i want the total paved area to be as large as possible.

how many pavers do i need?

step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
