First four terms would be n = 1, 2, 3, 4
f(1) = 3 ( 1 )( 1 + 3 )
= 3 * 4
=12
f(2) = 3 ( 2 )( 2 + 3 )
= 6 * 5
= 30
f(3) = 3 ( 3 )( 3 + 3 )
= 9 * 6
= 54
f(4) = 3 ( 4 )( 4 + 3 )
= 12 * 7
= 84 hope this helps!
So everything is 25%(1/4), in a regular price she would have paid $48. Good Luck
The apothem is the distance from the center to the midpoint of one of the sides of a regular polygon. You can make a right triangle with the apothem, the line from the midpoint to the corner and the line from the center to the corner. An equilateral triangle has 60 degree angles (180/3). The right triangle has half of one of those angles so 30 degrees. Now we have a 30-60-90 triangle where the short leg is 5cm. The long leg, which is also half of one side of the triangle is thus

. A whole side of the triangle is

. Multiply that by 3 to get the perimeter of <span>
