Answer:
Option A: 2338.3 cm² is the correct answer.
Step-by-step explanation:
Given that:
The given figure is a regular hexagon.
Length of side = 30 cm
Area of a hexagon is given by;
Area = 
Putting a=30 in the formula
Area = 
Area = 
Area = 
Area = 2338.26 cm²
Rounding off to one decimal place,
Area = 2338.3 cm²
Hence,
Option A: 2338.3 cm² is the correct answer.

Simplify the radical by breaking up the radicand up into a product of known factors, assuming positive real numbers.
Answers:
Domain = ![[-5, -2] \cup [1,5)](https://tex.z-dn.net/?f=%5B-5%2C%20-2%5D%20%5Ccup%20%5B1%2C5%29)
Range = ![(-4,4]](https://tex.z-dn.net/?f=%28-4%2C4%5D)
=============================================
Explanation:
The domain is the set of allowed x value inputs. We note that the left-most point is when x = -5, and this point has a closed or filled in endpoint, so we're including this x value in the domain.
The left piece has its other endpoint at x = -2, so the interval
is part of the domain. We write that as
is part of the domain's answer. The other part is
. We include x = 1 but exclude x = 5 as there's a hole here.
Use the union symbol to glue the two intervals together and we end up with
as the full domain.
----------------------------
The range is the set of possible y values. The lowest point is when y = -4, but we exclude this endpoint since there's an open hole here. The highest point is when y = 4. The range is
which we write as ![(-4, 4]](https://tex.z-dn.net/?f=%28-4%2C%204%5D)
Since there are no gaps in the range, we don't use any union symbols here. Any y value between -4 and 4 is possible, other than y = -4 itself.
