<h3><u>Required Answer</u><u> </u><u>:</u><u>-</u></h3>
Let the number of sides=x
As we know that in a polygon
Number of sides=40.
Answer:
40
Step-by-step explanation:
The sum of the exterior angles of a polygon = 360°
Divide this by the value of 1 exterior angle to find the number of sides n
n = 360 ÷ 9 = 40

Answer:
4x + 5 = 2x + 7
4x + 5 - 2x = 2x - 2x +7
2x + 5 = 7
2x + 5 - 5 = 7 - 5
2x = 2
2x÷2 = 2÷2
x = 1

Step-by-step explanation:
a = amount deposited at 3.5%
b = amount deposited at 4.5%
we know that "b" is twice as much as "a", thus b = 2a.
