6(13m+3-5/6m=-15)
78m+18-5m=-90
73m+18=-90
73m= -108
m = -108/73
Answer:
72 feet
Step-by-step explanation:
- The deck has 6 Sides
- Each side of the deck is 12 feet long
This is an example of a regular hexagon. A hexagon is a polygon that has 6 sides. It is regular because all the sides are equal.
Perimeter of a Regular Hexagon=6l
Length of one side, l=12 feet
Therefore:
Perimeter of the deck = 6 X 12 =72 feet
We are given coordinates of the triangle: A(2,2), B(7,1) and C(8,-4).
We need to rotated 90° counterclockwise about the origin.
In order to find the new coordinates of rotatation 90°counterclockwise about the origin, we can apply rule (h, k) ---> (-k,h).
Where (h,k) are the coordinates of original image on axes and (-k,h) are the coordinates of rotated image.
In resulting coordinates of the image first swap the x and y coordinates of the original image and then make the sign opposite of each x-coordinate.
On applying rule (h, k) ---> (-k,h), we get
A(2,2) --> A'(-2,2)
B(7,1) --> B'(-1,7)
C(8,-4) --> C'(4,8)
Division first (16\8)=2+10=12 (9+3 = 12 ) 12+12= 24
