Answer:
- Translation
Step-by-step explanation:
Movement of a rigid object from one place to another without any turning is "translation." If the object also changes its orientation angle, then rotation is involved.

Answer: 13
Step-by-step explanation:
5+2x
When x=4
5+2(4)
5+8
= 13
 
        
                    
             
        
        
        
ABC and HJK are congruent and the corresponding sides and angles are equal. Side HJ is congruent with side AB so HJ is also 3.5cm in length.
        
                    
             
        
        
        
Answer:
x=8
A = 192
Step-by-step explanation:
The perimeter is the sum of the outer lengths
17.9 + 22.6 + 3x = 64.5
Combine like terms
40.5 +3x = 64.5
Subtract 40.5 from each side
40.5 +3x -40.5 = 64.5 - 40.5
3x =24
Divide each side by 3
3x/3 = 24/3
x = 8
The area of a triangle is given by 
A = 1/2 bh
The base is 3x = 3(8) =24
and the height is 2x = 2(8) =16
A = 1/2 (24) * 16
A =192
