Answer:
b. 14
Step by step explanation:
We know that
The formula to <span>find the sum of the interior angles of a regular polygon is
</span>(n - 2)*180°
where n is the number of sides
so
clear n
(n - 2)*180° = 720°-----> (n-2)=720/180---> n-2=4----> n=6 sides
the answer is
6 sides
In the first statement, it is false. -2+14 would not add up to 16.
In the third statement, it is false. -8+-2 would not add up to 16.
In the fourth statement, it is false. -2-14 would not add up to 16.
So the second statement is true -2+18=16.
Answer:
x = 1
Step-by-step explanation:
The graph shows the curves cross at x=1.
The solution is x = 1.

<em>Additional comment</em>
I personally find it more convenient to look for the zeros (x-intercepts) of the difference f(x)-g(x). That way, I'm only graphing one function, and I don't have to look all over the graph to try to find the point of intersection. (The solution is always on the x-axis.) The attached graph shows f(x) - g(x) as a dashed green line.
V=(hπr^2)/3, π≈3.14, h=7, r=2
V≈29.3 cm^2
