The last three parts are coming with a question mark, so can't answer those parts. post the image or write it properly  
a) Every student is taking at least one course.  
 
  
So for all x, there is a y such that T(x,y) is a true will be given by the above statement  
b) There is a part-time student who is not taking any math courses.  
![\exists x \forall y [A(x) \Lambda (M(y) \rightarrow ~T(x,y))]](https://tex.z-dn.net/?f=%5Cexists%20x%20%5Cforall%20y%20%5BA%28x%29%20%5CLambda%20%28M%28y%29%20%5Crightarrow%20~T%28x%2Cy%29%29%5D)

Answer:8 and 12 
Step-by-step explanation: 8 is 4 less than 12 and 12 and 8 equals 20
 
        
             
        
        
        
3(m + 5 + 9m)
A.
(1) 3m + 15 + 27m
(2) 3(10m + 5)
B. 3(m + 5 + 9m)....distributive property
     (3 * m) + (3 * 5) + (3 * 9m) =
    3m +  15 + 27m
C. 3(m + 5 + 9m) = 3(10m + 5)......m = 1
     3(1 + 5 + 9(1) = 3(10(1) + 5)
     3(1 + 5 + 9) = 3(10 + 5)
     3(15) = 3(15)
     45 = 45
