((b1+b2)÷2)(h)=A
so I think the answer is 3 1/16 or 3.0625
        
             
        
        
        
Answer:
3.4 x 10^4
Step-by-step explanation:
1.6 x 10^4 - 5 x 10^4 = -3.4 x 10^4
5 x 10^4 - 1.6 x 10^4 = 3.4 x 10^4
 
        
             
        
        
        
I think the answer is c or d if im wrong sorry hope this helped tho :p
        
             
        
        
        
Answer:

Step-by-step explanation:
The diagonal of any square with side length  is equal to
 is equal to  . Since the side length of the square is 10, the diagonal must be
. Since the side length of the square is 10, the diagonal must be  .
.
To support and prove this:
The diagonal creates two 45-45-90 triangles, with the diagonal being the hypotenuse of both of these triangles. The Pythagorean Theorem states that in any triangle, the sum of the squares of both legs is equal to the square of the hypotenuse ( ).
).
Call the diagonal  . In these two triangles, both legs are equal to 10 (the side lengths of the square), and the hypotenuse is the diagonal. Thus, we have:
. In these two triangles, both legs are equal to 10 (the side lengths of the square), and the hypotenuse is the diagonal. Thus, we have:

 
        
                    
             
        
        
        
<span>2x+12+6x+1-x
You are adding up 2x and 6x and deduct 1x so you get 7x
You add up 12 and 1 which gives 13</span>
