Which expressions are equivalent to 4(4a+5) ? choose 3 answers: (choice a) 16a+5 (choice b,) 16a+20 (choice c) 12a+20+4a (choice d,) 2(8a+10) (choice e) 16a+5+4

The correct answer is B

Step-by-step explanation:4(4a + 5)

Use the distributive property

(4)(4a) + (4)(5)

16a + 20

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
