Answer:
shaded area  = 601 mm² 
Step-by-step explanation:
Area of rectangle = Length * Breadth
Area of first section = 12 * 16 = 192 mm²
Area of 2nd middle section = 8 * ( 16 - 10 ) =  48 mm²
Area of the bottom section = 19 * 19 = 361 mm²
Area of total therefore = 192 mm² + 48 mm² + 361 mm² 
                                       =  601 mm² 
 
        
                    
             
        
        
        
Answer:
An angle bisector is a line passing through the vertex of the angle that cuts the angle into two equal smaller angles.
Given: MN is angle bisector, 
then  
 .......  [1]
            .......  [1]
Congruent angles are  two or more angles that have the same measure.
then;
by definition of congruent angles 
[1]⇒  ......[2]
                ......[2]
By the  Angle addition postulates states that if M is in the interior of ∠JMK then,
  ......[3]
            ......[3]
Now, by substitution property ; substitute the equation [2] in [3] we get;
  ......[4]
                 ......[4]
Like terms terms whose variables  are the same
Combine like terms in equation [4] we get
  ......[5]
                      ......[5]
Division property of equality states that you divide the same number to both sides of an equation.
Divide by 2 to both sides in equation [5] , we get

Answer:
-2(16xy-10y+7)
Step-by-step explanation:
-2(16xy-10y-7)= -2×16xy-2(-10y)-2×7
-2(16xy-10y+7)= -32xy+20y-14
