Answer: 22
Step-by-step explanation:
For any regular polygon there is a result which says that the number of lines of symmetry of a regular polygon is equal to its number of sides because:-
Case 1: If the number of sides is a <em>odd number</em>, then there are lines of symmetry which can be create from each vertex to the midpoint of the opposite side.
Case 2: If the number of sides is a <em>even number</em>, then there are lines of symmetry which can be create from each vertex to the opposite vertex and another line which can be create from mid-points of opposite sides.
Therefore, if a regular polygon has 22 sides
Then the number of line of symmetry = 22
-5/9 + -7/12
= -5/9 - 7/12
LCD os 9 and 12 is 36 so we have
-20/36 - 21/36
= -41/36
Answer:
-1/2 or x=2
Step-by-step explanation: The first step you need to do in getting your answer is factoring ,you will factor the left side of the equation first:
(2x+1)(x-2)=0
Next, you will set the factors to equal to "0":
2x+1=0 x-2=0
Then you'll proceed to solve the problem using the basic algebraic equation problem solving steps .When you do this you'll be left with answers of x=-1/2 and x=2
The graph y=5-x contains the points (2,3) and (3,2). 3=5-2 is true and 2=5-3 is true, so (2,3) and (3,2) are on the graph.
2.96 = 2 96/100 = 2 24/25
