A = (1/2) b* h
OR
A = (b*h)/2
 A = (8* 2)/2
A = 16/2
A = 8 yd^2

For number 7 since the rational number is countable, and the set of real numbers is uncountable, almost all real numbers are irrational. So you should choose false 
8 yes! All whole numbers are integers. For an example 0 is a whole number, 0 Is ALSO a integer. So you should choose truth
        
                    
             
        
        
        
Answer:
A
Step-by-step explanation:
I think it is A because if you do the math when your double her time she has way more distance.
 
        
             
        
        
        
What you do is you distribute the 5.
So your answer would be 5x+15
        
                    
             
        
        
        
Answer:
    8 and 12
Step-by-step explanation:
Sides on one side of the angle bisector are proportional to those on the other side. In the attached figure, that means
   AC/AB = CD/BD = 2/3
The perimeter is the sum of the side lengths, so is ...
   25 = AB + BC + AC
   25 = AB + 5 + (2/3)AB . . . . . . substituting AC = 2/3·AB. BC = 2+3 = 5.
   20 = 5/3·AB
   12 = AB
   AC = 2/3·12 = 8

<em>Alternate solution</em>
The sum of ratio units is 2+3 = 5, so each one must stand for 25/5 = 5 units of length. 
That is, the total of lengths on one side of the angle bisector (AC+CD) is 2·5 = 10 units, and the total of lengths on the other side (AB+BD) is 3·5 = 15 units. Since 2 of the 10 units are in the segment being divided (CD), the other 8 must be in that side of the triangle (AC). 
Likewise, 3 of the 15 units are in the segment being divided (BD), so the other 12 units are in that side of the triangle (AB).
The remaining sides of the triangle are AB=12 and AC=8.
