Plz ! josh's teacher draws a regular octagon on a coordinate plane. one side has endpoints at (1,5) and (4,5). josh says he can't find the perimeter of the octagon because he can only find lengths of horizontal and vertical segments. he says he can't find the lengths of the slanted sides of the octagon. what mistake is josh making? what is the perimeter of the octagon?

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
