Answer:
AA similarity theorem 
Step-by-step explanation:
we know that
<u>AA (Angle-Angle) Similarity</u> states that  In two triangles, if two pairs of corresponding angles are congruent, then the triangles are similar
In this problem we have that
∠BCA=∠ECD ----> by vertical angles
∠BAC=∠DEC ---> because AB is parallel to ED (alternate interior angles)
therefore
Triangles ABC and EDC are similar by AA similarity theorem 
 
        
             
        
        
        
use the order of operations for this equation.
multiplication comes first.
11(11) - 6(17) + 4
121 - 102 + 4
for addition and subtraction, order doesn’t matter.
121 - 102 = 19
19 + 4 = 23
answer = 23
 
        
             
        
        
        
First add the prices of the original books.
2.5+4.95+6=11.45
Find 20% of 11.45
=2.29
Therefore I saved $2.29
