Find the product
(7x + 3)2

14x + 6

Step-by-step explanation: because with the expression (7x +3)2 you would first use the distributive propert, and multiply the numbers inside of the parentheses by the outside number. So, 2 * 7x= 14x. And then 2 * 3= 6. so it would be 14x + 6.

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
