Answer:
Qualitative variable
Step-by-step explanation:
The response is qualitative variable due to its possible categories. In short, the response can only be divided into categories and cannot be interpreted numerically in a meaningful way. Thus, response is a qualitative variable. Also, the categories involves ordering like better and worse etc so, the measurement of scale would be ordinal in this scenario.
 
        
             
        
        
        
-4d + 2(3+d)= -14
distribute the 2(3+d)
-4d + 6+ 2d= -14
Combine the like terms
-4d + 2d + 6= -14
-2d + 6 = -14
subtract 6 to -14 
-2d = -20
divide by -2
d= -20/-2
d= 10
Check your answer 
-4(10) + 2(3+ 10) = -14
-40 + 6 + 20
-40 + 26= -14
