9=(1/27)^(a+3)
3^(2)=(3^(-3))^(a+3)
2=-3(a+3)
2=-3a-9
2+9=-3a
11/-3=a
a=-11/3

Formula of a polygon: A= 1/2ap

a = apothem

p = perimeter

Since the polygon has 7 sides, you need to multiply 7 by 7.7 (side length) to find the perimeter which would be 53.9

A= 1/2 x 8 x 53.9

A = 215.6 meters

Between which two consecutive integers is the negative square root of 5

kogti [31]

Answer: Between the numbers -2 and -3

Step-by-step explanation:

The negative square root of 5 will be slightly greater than 2 because the square root of 4 is 2 and 5 is greater than 2. The negative square root of 5 will not be greater than -3 because 3 squared is 9. So it has to be between -2 and -3.
