Sam is handing out advertisements for an upcoming event. He starts with a box of 5,000 advertisements and hands out 12 advertisements per minute, on average. Which of the following equations best models the
relationship between the amount of time t, in minutes, Sam spends handing out advertisements and the
number of advertisements, n, remaining?
A t = 5,000n - 12
B
n = 5,000t - 12
t = 5,000 - 12n
D
n = 5,000 - 12t

2 equivalent expressions to represent the area of a rectangle and the top is n-3 and the side is 2

area of the rectangle = length * width

given length = n - 3

width = 2

replace it in the area

so area of the rectangle = (n-3) *2

= 2(n-3)

one of the expression is 2(n-3)

to get another expression we distribute 2 inside the parenthesis

2(n-3) is 2n - 6

so another expression is 2n - 6

two equivalent expression are

2(n - 3)   , 2n - 6

it would be c. 25 units
