Step-by-step explanation:
Answer:
3. 3 : 5; 3: 5
Step-by-step explanation:
First, let's find the leght of the sides of each octagon.
The area of an octagon is defined by
Replacing the area
Therefore, the side of the first octagon is 1.6 inches long.
Its perimeter is:
Therefore, the side of the second octagon is 3.8 inches long.
Its perimeter is .
Now, let's divide to find each ratio:
(the ratio between sides).
(the ratio between perimeters).
Therefore, the closest ratio is 3. 3 : 5; 3: 5
<span>ROS+SOT=30 28' 10"
ROS+ROT+SOT=180
ROT=180-(ROS+SOT)= 150 32' 50"</span>
-6x + 4 = -124
First bring 4 to the right side by subtracting 4 to both sides (what you do on one side you must do to the other). Since 4 is being added on the left side, subtraction (the opposite of addition) will cancel it out (make it zero) from the left side and bring it over to the right side.
-6x + 4 - 4 = -124 - 4
-6x + 0 = -128
-6x = -128
Now to completely isolate x you must divide -6 to both sides. Since -6 is being multiplied by x, division (the opposite of multiplication) will cancel -6 out (in this case it will make -6 one) from the left side and bring it over to the right side.
-6x/-6 = -128/-6
1x =
^^^The fraction can be simplified further
x =
x ≈ 21.33
