Answer:
y = - 3
Step-by-step explanation:
Locate x = 2 on the x- axis, then go down vertically to meet the line. At this point read off the corresponding value on the y- axis, thus
The value of the function at x = 2 is y = - 3
 
        
             
        
        
        
Reflection across the line y=x simply swaps the x and y coordinates.

Answer:
 and
 and 
Step-by-step explanation:
At=As+Ar; A=b.h and  , then:  At=(x+120)x so
, then:  At=(x+120)x so 
(x+120)x=4500,  Applying cuadratic equation formula:
 Applying cuadratic equation formula:
 
        
                    
             
        
        
        
Given:
The side of a square is,

Required:
To find the perimeter of a given square.
Explanation:
In square, all the sides are equal.
Therefore, all sides are (s+3).
To find perimeter, we need to add all the sides,
Therefore,

Final Answer:
Option (d) is correct.
 
        
             
        
        
        
Answer: A
Step-by-step explanation: 
A rhombus is a quadrilateral with all sides equal in length. A square is a quadrilateral with all sides equal in length and all interior angles right angles. Thus a rhombus is not a square unless the angles are all right angles. ... A square however is a rhombus since all four of its sides are of the same length. 
A square is a quadrilateral with all four angles right angles and all four sides of the same length. So a square is a special kind of rectangle, it is one where all the sides have the same length. Thus every square is a rectangle because it is a quadrilateral with all four angles right angles.
