D. A rectangle and an isosceles triangle
Step-by-step explanation:
In the figure attached, the sign is shown. There we can see an arrow, which can be decomposed into a rectangle (on the left of the figure) and an isosceles triangle  (on the right of the figure) 
 
        
             
        
        
        
Answer:
This means c=100. The factored form is  .
.
Step-by-step explanation:
A perfect square is a trinomial that factors into the form  . To find the value of C to finish the perfect square divide 20 by 2 and square it.
. To find the value of C to finish the perfect square divide 20 by 2 and square it.
20/2 = 10
10*10=100
This means c=100. The factored form is  .
