a_{n} = a₁ + d(n - 1)

In the given problem, a₁ = 15 and d = 3

a_{n} = 15 + 3(n - 1)  = 15 + 3n - 3   = 3n + 12

a_{56} = 3(56) + 12  = 168 + 12   = 180

Answer: a_{n} = 3n + 12, 180

ICE Princess25 [194]
First, find 12% of $8.50.

12% of $8.50 = 12% * $8.50 = 0.12 * $8.50 = $1.02

The raise is $1.02 per hour.

$8.50 + $1.02 = $9.52

Pepsi [2]

Step-by-step explanation:

first of all, your teacher wrote nonsense in the answer options : an area is always given in squared units. never in cubed units (which would be volume).

the area is : 1/2 × perimeter × apothem

the perimeter is simply 12 × 5 = 60 meters.

apothem = (a/2)×cot(pi/12) = 5/2 × cot(pi/12) =

= 9.330127019... meters

so the area is

1/2 × 60 × 9.330127019... = 279.9038106... m²

therefore, the third answer option is correct (although it is m², and not m³).

by the way, you have question 3 wrong. I answered this with the correct apothem calculation in the explanation for question 4.
