12.325-(2.34x3.9)
12.325-(9.126)
3.199 ~3.2
        
             
        
        
        
Start with parenthesis first.
so a+a+2a+48
Then add all like terms.
4a=48
Then solve for a by dividing 4 from 48.
a=12
        
             
        
        
        
B. 10 ft per minute
because the line is steadily increasing at a constant rate yeah, it's 10 feet per minute
 
        
                    
             
        
        
        
Answer:
The equation of the line is y = -1.5x + 3
The y-intercept is (0,3)
The value of k is 3.
Step-by-step explanation:
y - 0 = -1.5 (x - 2)
y = -1.5x + 3

Answer:
   {4, 5, 6, 7, 8}
Step-by-step explanation:
The inequality related to the perimeter is ...
   x +(x +4) +11 < 32
   2x < 17 . . . . . . . . . . . . subtract 15
   x < 8.5
The inequality related to the triangle inequality is ...
   (x) +(x +4) > 11
   2x > 7
   x > 3.5
Then possible whole-number values of x are ...
   {4, 5, 6, 7, 8}
