Answer: A line that is a perpendicular bisector of AB
Step-by-step explanation:
The given picture is of regular heptagon .
There are seven lines of symmetry for a regular heptagon.
Line of symmetry of regular heptagon are those lines which intersect each vertex and the mid point of opposite side .
Therefore, only fourth option is giving the right answer.
A line that is a perpendicular bisector of AB is the line of reflection which can regular polygon ABCDEFG reflect to map onto itself .
The process is to go step-by-step to isolate the y.
To do this, you basically run the order of operations in reverse.
In 5x+2y=10, the first thing to move away from the left side is 5x and you cancel it out by subtracting 5x from both sides:
5x+2y - 5x = 10 - 5x
The 5x's on the left cancel leaving you with:
2y = 10 - 5x
Side note: this is more commonly written as 2y = -5x+10, since we tend to write variable terms first.
Finally, to get the y fully by itself, you need to cancel the 2 that's multplied against it. To cancel multiplication, you need to divide:
The most important thing to remember here is that the 2 needs to divide into both terms on the right:
Finally, we simplify this into:

Step-by-step explanation:
(6x+14)(x-8) = Expand
6x^2 - 48x + 14x - 112 =
6x^2 - 34x-112 A = 6 B = -34
Answer:

Answer:
diameter = 2.5 feet
Step-by-step explanation:
Circumference of a circle is given as C = πd
Circumference of the tree trunk = 7.85 ft
π = 3.14
Diameter of the tree trunk = d
Thus:
7.85 = 3.14*d
Divide both sides by 3.14
7.85/3.14 = 3.14*d/3.14
2.5 = d
d = 2.5 ft
