Answer:

The answer is 3,240

Step-by-step explanation:

In geometry, an icosagon or 20-gon is a twenty-sided polygon. The sum of any icosagon's interior angles is 3240 degrees.

In mathematics, the interior angles of a polygon are the angles on the inside of the polygon created where the sides of the polygon meet. When a polygon is a n-sided regular polygon, meaning it has n sides, its sides have the same length, and its angles have the same measure, we have that the measure of one interior angle is given by the formula $180 -\frac{360}{n}$

Answer:

The answer to your question is Area = 6 u²

Step-by-step explanation:

Process

To find the area of the picture divide the figure between a square and a right triangle, determine the area of each figure and finally add them up.

1.- Calculate the area of the square

Area = side x side

= 2 x 2

= 4 u²

2.- Calculate the area of the triangle

Area = base x height / 2

base = 2 height = 2

Area = 2 x 2 /2

Area = 2 u₂

3.- Total area

Area = 4 + 2

= 6 u²

We have the expressions:

$f(x)=x^2+6x+15$ $y=x^2-4x+9$ $f(x)=x^2-8x$ $y=x^2+7x-2$

Now, with this we operate as follows:

a)

$f(x)=x^2+6x+15=x^2+6x+9+15-9$ $\Rightarrow(x+3)^2+6$

Then, the axis is x = -3 and the vertex (-3, 6)

b)

$y=x^2-4x+9=x^2-4x+4+9-4$ $\Rightarrow(x-2)^2+5$

Then, the vertex is (2, 5) and the axis is x = 2.

c)

$f(x)=x^2-8x+4-4\Rightarrow(x-2)^2-4$

Then, the vertex is (2, -4) andd the axis is x = 2.

d)

$y=x^2+7x-2=x^2+7x+\frac{49}{4}-2-\frac{49}{4}$ $\Rightarrow(x+\frac{7}{2})^2-\frac{57}{4}$

Then, the vertex is (-7/2, -57/4) and the axis is -7/2.
