Question

A film set designer is using white and colored tiles in a pattern to create paths of different lengths. If x is the length of the path in feet, the number of colored tiles needed to make it is calculated using the rule

(8x2y2)(3xy)

where y represents the number of white tiles.

Which simplified expression represents the number of colored tiles used for a path of length x feet?

24x3y3
11x3y3
24x2y2
11x2y2

Answer 1

@phi any help

Answer 2

@Jacob902 ??

Answer 3

they want you to multiply (8x2y2)(3xy)

surely you can multiply the two "pure" numbers
what do you get ?

Answer 4

24x3y3

Answer 5

yes you get 24, and yes the x^2 * x gives x^3 and ditto for the y's

Answer 6

so its A?

Answer 7

if you remember that x^2 is short for x*x
and if you multiply by another x you get
x*x*x

you could write the answer as
24*x*x*x*y*y*y
but people use the "short way" to write it
24 x^3 y^3

Answer 8

OK

Answer 9

The life spans, in years, of some plants in a nursery are shown below:

5, 3.2, 4.1, 3.8, 3.1, 3.2, 5.8, 3.8, 4.2, 4.3

Jack made the following box plot to represent the life spans:
