11. (07.03 LC) A film set designer is using white and colored tiles in a patter 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
(4x?y?)(3x?y?)
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? (5 points)
Oxys
7X45
12x^ys
12y

i believe the answer is 68cm

step-by-step explanation:

i just took 34 x 2 because the space between v and y is the same as y to k.

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
