Answer:
11 
Step-by-step explanation:
Substitute 3 for b 
23 - 4(3) 
Multiply 4(3) = 12 
23 - 12
Subtract 
23 - 12 = 11 
 
        
                    
             
        
        
        
Answer:
38.60mm
Step-by-step explanation:
Step one:
Given data
We are given that the dimension of the triangles are length 23 mm and 31 mm
Let us assume that the triangle is a right angle triangle
Step two:
Applying the Pythagoras theorem we can find the third as

square both sides
z= √ 1490
z= 38.60mm
Hence a possible dimension of the third side is 38.60mm
