Well we know she filled up her car 11 times each with 14 gallons.
All we have to do is multiply 11 by 14
11 x 14 = 154
Now the question says to estimate. And our answer can be rounded down to 150 gallons. 
So your answer is..
B.) 150 gallons. 
Good Luck! :)
        
                    
             
        
        
        
|AC| = 2|DE|
⇒
4x - 2 = 2(x + 6) = 2x + 12
2x = 14
x = 7
⇒
|AC| = 26

Answer:
Step-by-step explanation:
1.  The slope is -5/2
2. There is no slope for the second one it's just y=3
3. The slope is 3
4. These are perpendicular lines
5. These lines are parallel.
6. These lines are neither perpendicular nor parallel.
7. These lines are perpendicular
8.  y = 4/3x - 2
9.  y = -1/2x + 5
10. x = -1  
Hope this helps!
 
        
             
        
        
        
   
P = 12 + 6 + 8,5 = 18 + 8,5 = 26,5 mm
A = 12 × 4 / 2 = 48 / 2 = 24 mm²
