Answer: Hello, there! Sorry Im late But your answer is Below

30 sides Would be the correct answer

Step-by-step explanation:

t has 30 sides. The formula (n-2)×180 can be used to find the sum of the interior angles of ANY polygon where n is the number of sides in the polygon.

Hope this Helps!!

Have a great day!!!

Answer:

x = 0

y = -12

Step-by-step explanation:

Plug in what y is equal to into the second equation

-3(x - 12) = 2x + 36

Distribute the -3

-3x + 36 = 2x + 36

-36 -36

-3x = 2x

They cannot be equal so x = 0

Plug in 0 into the y equation

y = 0 - 12

y = -12

A rectangular garden has an area of 24 square meters. The width is 8 meters less than twice the length. Find the dimensions of t

OLEGan [10]

Answer:

Length: 6 m

Width: 4 m

Step-by-step explanation:

Area: 24 $m^{2}$

Width: 2L - 8 m

Length: ?

Formula: A = W * L

Replace the variables:

24 = (2L - 8) * L

24 = 2 $L^{2}$ - 8L

0 = 2 $L^{2}$ - 8L - 24

2 $L^{2}$ - 8L - 24 = 0

Solve; if you don't know how to solve it using this method, let me know. It's the expression $Ax^{2} +Bx+C$

1. $2 (\frac{(2L^2 - 8L - 24)}{2})$

2. $\frac{(2L)^2 - 8(2L) - 48}{2}$

3. $\frac{(2L - 12)(2L + 4)}{2}$

4. $2(\frac{(L - 6)(2L + 4)}{2})$

5. (L-6) (2L+4)

6. L-6 = 0 AND 2L+4 = 0

L - 6 =0

L = 6

---------------------------------

2L = -4

L = $\frac{-4}{2}$

L = -2

Since the length cannot be negative, the only real value is 6.

Area: 24 $m^{2}$

Width: 2L - 8 m

Length: 6 m

Calculate width:

W = 2L - 8

W = 2(6) - 8

W = 12 - 8

W = 4 m

NISA [10]

Answer:

15 = 7 + m

Step-by-step explanation:

If 15 is the total then it goes on the other side of the equal sign. You have one side so if you add it to the missing side it should equal 15.
