Answer:
D
Step-by-step explanation:
The answer is point D(-2,1).
1. If the point D was moved down 2 units, then its coordinates became (-2,-1).
2. If point (-2,-1) was reflected over the x-axis, then its coordinates became (-2,1).
3. If the point (-2,1) was moved 4 units to the right, then its coordinates became (2,1).
4. If point (2,1) was reflected over y-axis, its coordinates became (-2,1).

Step-by-step explanation:
17.
the triangle of sides ‘l’ and ‘l-h’ is a right angled triangle.
Then

Then

Then

18.
For l = 6  and  θ = 40 :

   = 6-6cos(40)
   = 1.403733341286
 
        
             
        
        
        
Answer:
perimeter of figure = 24.28
Step-by-step explanation:
semicircle ' s perimeter = π r = 3.14 × 2 = 6.28 cm
perimeter of 3 sides of parallelogram = 7 +7+4= 18 cm.
perimeter of figure = 18 +6.28 = 24.28 
approx value = 24.30 cm
 
        
             
        
        
        
It is not factored completely because it was only factored by 3ab but it could have been factored by 6a²b
6a²b(a+6+8a²)
