Answer:

The area of the regular nonagon is 7921.8 square inches.

Step-by-step explanation:

Geometrically speaking, the area of a regular polygon is determined by following area formula:

[tex]A = \frac{p\cdot a}{2}[/tex] (1)

Where:

[tex]A[/tex] - Area of the regular polygon, in square inches.

[tex]p[/tex] - Perimeter, in inches.

[tex]a[/tex] - Apothem, in inches.

If we know that [tex]p = 162\,in[/tex] and [tex]a = 97.8\,in[/tex], then the area of the regular nonagon is:

[tex]A = 7921.8\,in^{2}[/tex]

The area of the regular nonagon is 7921.8 square inches.

Answer: [tex]412000000\ cm^3[/tex]

Step-by-step explanation:

Given

Number is [tex]412\ m^3[/tex]

we know

[tex]1\ m=100\ cm\\\\\therefore 1\ m^3=1000000\ cm^3[/tex]

For [tex]412\ m^3[/tex] it is

[tex]\Rightarrow 412\ m^3=412\times 1000000=412000000\ cm^3[/tex]

Answer:

36

Step-by-step explanation:

The sum of the angles of a triangle is 180 degrees

<A+ <B+ <C = 180

2x+6x+2x = 180

10x = 180

Divide by 10

10x/10 = 180/10

x = 18

We want to find <C

<C = 2x

     = 2*18

    = 36

Answer: -4/12 or -1/3

Step-by-step explanation:

Use the formula y1 - y2/x1 - x2

It doesn’t matter which point you use as your x1 or x2 as long as you as consistent and use the same equation for the x and y.

Answer:

yes their just 2 answer choices

Answer:

x=-2

Step-by-step explanation:

Let's solve your equation step-by-step.

5(x+6)+11=25−3x

Step 1: Simplify both sides of the equation.

5(x+6)+11=25−3x

(5)(x)+(5)(6)+11=25+−3x(Distribute)

5x+30+11=25+−3x

(5x)+(30+11)=−3x+25(Combine Like Terms)

5x+41=−3x+25

5x+41=−3x+25

Step 2: Add 3x to both sides.

5x+41+3x=−3x+25+3x

8x+41=25

Step 3: Subtract 41 from both sides.

8x+41−41=25−41

8x=−16

Step 4: Divide both sides by 8.

8x

8

=

−16

Answer:

The answer is B

Step-by-step explanation:

Hope this helps!

Answer:

The answer is -8 and 8

Step-by-step explanation:

no.1 first write the equation

the write the sum and the product

so the sum will be 8x and the product

will be 15.In the product part look for a no

that when you multiply it by another no

it will give you 15 by when you add it will

become 8.The no.is 5 and 3.you now rewrite the equation x^2+3x+5x+15=0

you now simply the equation x(x+3)+5(x+3)

you take (x+3)and (x+5)=0.

your answer will either be -3or-5 respectively

Answer:

6(3+8)

Step-by-step explanation:

6(3+8)= 6×3+6×8=18+48

this is the given value of A

The correct expressions for total area = 6x3 + 6x8 or 6(3+8)

Rectangles are four-sided polygons with all internal angles equal to 90 degrees. At each corner or vertex, two sides meet at right angles. The rectangle differs from a square in that its opposite sides are equal in length.

In the given figure,

Area of one room = 18 square feet

Area of second room = 48 square feet

Now since we can see that,

the width of both rooms is same,

therefore,

we have 6 as common factor of 18 and 48

As, 18 = 6x3

      48 = 6x8

Total are of the given figure = 18 + 48

Since we know that,

Area of rectangle = length x width

Therefore,

area of both rooms  = 18 + 48

                                 = 6x3 + 6x8

                                 = 6(3+8)

Hence,

The rooms total area of both rooms = 6x3 + 6x8 or 6(3+8)
