Answer:
21
Step-by-step explanation:
Try using this notation: a(n) and not an.
an=n^3-2n becomes a(n) = n^3 - 2n.
Then a(1) = 1^3 - 2(1) = 1 - 2 = -1
a(2) = 2^3 - 2(2) = 8 - 4 = 4
a(3) = 3^3 - 2(3) = 27 - 6 = 21
The area of a parallelogram is length x height.
The answer would be C. A = 12 • 8
8x3
3x8
4x6
6x4
2x12
12x2
1x24
24x1
<em>x = 0.04979</em>
ln x = -3
x = e^(-3)
x = 1/e^3
x = 0.04979
80
