Answer:
The Z is has no lines of symmetry. The W and Y have one line of symmetry. The X has two lines of symmetry.
Is this suppose to be an equation or is there something missing here?

L*w=20, so l=20/w
l=2w+3
20/w=2w+3
20=2w^2+3w
2w^2+3w-20=0
Slip and slide
w^2+3w-40
(w+8)(w-5)
(w+8/2)(w-5/2)
(w+4)(2w-5)
w= -4 or 5/2, but since width must be positive, it is 5/2
(5/2)*l=20
l=8
Final answer: Length= 8, Width= 5/2
Answer:
The coordinates of D are (-3,-7).....
Step-by-step explanation:
First we have to find the coordinates of B. For this we will take the average of the two points that make up the segment. We will take A and C.
Average of x's value
-9+(-1) = -9-1 = -10/2 = -5
Average of y's value
-4+6 = 2/2 = 1
Thus the coordinates of B are (-5,1)
Now we will find the coordinates of D. Here E is the average of B and D. Thus the solution will be:
B+D/2= E
Average of x's
-5+D/2 = -4
-5+D = -4*2
-5+D = -8
D= -8+5
D= -3
Average of y's
(B + D)/2 = E
1 + D/2 = -3
1 + D = -6
D = -7
Thus the coordinates of D are (-3,-7).....
