The perimeter of a rectangular pool is 258 m. If the width of the pool is 51 m, what is its length?

78

Step-by-step explanation:

Im 99% sure this is right because

51x2=102

258-102=156

156÷2=78

^•^

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
