The third dot is my answer. But don't take it for granted. Try it yourself and see what you come out with!
        
             
        
        
        
When you plug in the numbers for the integers, you get
8.2-2(-3.7)
If you multiply -2 and -3.7, you get 7.4 because the negatives cancel each other out.
If you then add 8.2, you get 15.6. So the answer is D.
Hope it Helps!  :)
        
             
        
        
        
The area of the given diagram is 29.817 square centimeters. The given diagram is combination of rectangle and semi circle.
Step-by-step explanation:
The given is,
                  Given diagram is combination of Rectangle and Semi circle.
Step:1
          Res the attachment,
                        Area of given diagram = Area of A + Area of B..............(1)
Step:2
          For A,
          The A section in the given diagram is semi circle,
                      Diameter of semi circle = Total distance - ( 2+3)
                                           ( ∵ 2, 3 are top distance in the given diagram)
                                                              
                                         Diameter, d = 5 cm
                                              Radius, 
                                                           
                                                          r = 2.5 cm
                                           Area,  ........................(2)
........................(2)
                                                      
   
                                                             
 
                                                            
                                                      
Step:3
                For B,
                 Area of rectangle is,
                                                        .....................(3)
.....................(3)
               Where, l - Length = 10 cm
                           b - Width = 2 cm
               Equation (3) become,
                                                             
                                                             
                                     Area of B,  = 20
 = 20 
Step:4
                From the equation (1),
                                Area of given diagram = 20+ 9.81747
                                                             Area = 29.817 square centimeters
Result:
             The area of the given diagram is 29.817 square centimeters. The given diagram is combination of rectangle and semi circle.
 
        
             
        
        
        
Using the speed - distance relationship, the time left before the appointed time is 27 minutes. 
<u>Recall</u><u> </u><u>:</u>
<u>At</u><u> </u><u>10mph</u><u> </u><u>:</u>
- Distance = 10 × (t + 3) = 10t + 30 - - - (1)
<u>At</u><u> </u><u>12</u><u> </u><u>mph</u><u> </u><u>:</u>
- Distance = 12 × (t - 2) = 12t - 24 - - - - (2)
<em>Equate</em><em> </em><em>(</em><em>1</em><em>)</em><em> </em><em>and</em><em> </em><em>(</em><em>2</em><em>)</em><em> </em><em>:</em>
10t + 30 = 12t - 24 
<em>Collect</em><em> </em><em>like</em><em> </em><em>terms</em><em> </em>
10t - 12t = - 24 - 30
-2t = - 54 
<em>Divide</em><em> </em><em>both</em><em> </em><em>sides</em><em> </em><em>by</em><em> </em><em>-</em><em> </em><em>2</em>
t = 54 / 2 
t = 27 
Hence, the time left before the appointed time is 27 minutes.
