Let P= $75, r=0.0054166, n= 40. In the future worth formula, F= P((1+r)^(n-1) -1) / r, it would yield a future worth of 3,247.16 at the age of 65. And the interest rate is I= (r^n-10)/(r-1). It yields an interest of 1.033
No, all regular polygons does not have even number of sides.
Suppose, heptagon which is a regular polygon which has 7 sides.
But, all the sides of any regular polygon are equal in length.
Answer:
160 inches
Step-by-step explanation:
Area = L times W
In a rectangle, there are 4 sides
2 are width
2 are length
56 is total
8 + 8 = 16
56 - 16 = 40
40 is what is left for the 2 length sides
since there are 2 sides and they need to be equal, we divided 40 by 2
40 / 2 = 20
the length of one side is 20
area = 8 times 20
a = 160 inches
If they want you to find the perimeter I guess you add all sides so 9+9+9+9+30 = 66
