Write an equivalent expression for the expression (a+b)(2+y)

2a+ay+2b+by

Step-by-step explanation:

(a+b)(2+y)

=(a+b)(2+y)

=(a)(2)+(a)(y)+(b)(2)+(b)(y)

=2a+ay+2b+by

=ay+by+2a+2b

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
