Answer:
16 sides
Step-by-step explanation:
the sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
here sum = 2520° , then
180° (n - 2) = 2520° ( divide both sides by 180° )
n - 2 = 14 ( add 2 to both sides )
n = 16
the polygon has 16 sides

Given the arithmetic sequence an = 4 − 3(n − 1), what is the domain for n? All integers where n ≥ 1 All integers where n > 1 All integers where n ≤ 4 All integers where n ≥ 4.
All integers where n ≥ 1.
We have given that the sequence,
[tex]a_{n} =4-3(n-1)[/tex]
We have to find the domain for n.
What is the meaning of arithmetic sequence?Arithmetic sequence is a sequence of numbers such that the difference between the consecutive terms is constant. Difference here means the second minus the first.
That is, [tex]a_{n} =a+(n-1)d[/tex]
where a = first term of sequence.
d =common difference.
n =number of terms which belongs to natural numbers
By the definition of arithmetic sequence n starts with 1
Remember that,the natural number starts with 1
Now, in given sequence for nth term
[tex]a_{n} =4-3(n-1)[/tex]
The domain for n is All integers where n ≥ 1.

A square picture has a 2-in. frame around it. If the area of the frame alone is 72 in .2, what is the area of the picture?
The area of the picture is 68 square inches
How to calculate the area of a squareGiven the following parameters
Area of the frame alone = 72 square inches
Area of the square picture = 2 * 2 = 4 square inches
Determine the area of the picture
Area of the picture = 72 square in - 4 square in
Area of the picture = 68 square inches

tan60 = √3 = 28/EG
=> EG = 28/√3 = 28/1.73
=> EG = 16.2 in.
sin60 = √3/2 = 28/EF

if f(x) = 2 - x^1/2 and g(x) = x^2 – 9, what is the domain of g(x) divided f(x)?
~Shoto Todoroki here~
Let's consider what we are asked. The domain is defined as a set of points that satisfy the equation on the x-ordinate.
So, essentially, we need to find if and what the restriction on x is.
Let's now consider just f(x) because g(x) is completely irrelevant to the question.
f(x) = 2 - x^(1/2)
Since f(x) can never be 0 for a defined function, let's consider when f(x) = 0 to find a restriction on x.
2 - x^(1/2) = 0
2 = x^(1/2)
+-4 = x
But we can only take the positive 4 because inside a square root has to always be positive (unless you're dealing with complex numbers), so the only restriction is that x cannot be equal to 4.
Therefore, our domain is: x >= 0; x =/= 4hope this helps :D

Step-by-step explanation:
Lateral SA = area of the 4 triangles
Formula to be used :-
Area (triangle) = 1/2bh
=> 4 x 1/2 x 9 x 12
=> 108 x 2
=> 216 cm²
Total SA = LSA + area of the square
Formula to be used :-
Area (square) = side length x side length
=> 216 + 9 x 9
=> 216 + 81
=> 297 cm²
The correct option is (D).
