Answer:
The correct answer is 90
Step-by-step explanation:
17 + 36= z- 37   ADD 17 AND 36
 53= z-37        BRING 37 OVER TO 53 AND ADD
z = 90           FINAL ANSWER
 
        
             
        
        
        
Answer:
146.41
Step-by-step explanation:
third order determinant = determinant of 3×3 matrix A
given ∣A∣=11
det (cofactor matrix of A) =set (transpare of cofactor amtrix of A) (transpare does not change the det)
=det(adjacent of A)
{det (cofactor matrix of A)}  ^2  = {det (adjacent of A)}
^2
  
(Using for an n×n det (cofactor matrix of A)=det (A)^n−1
)
we get
det (cofactor matrix of A)^2  = {det(A)  ^3−1
}^2
  
=(11)^2×2  = 11^4
  =146.41
 
        
             
        
        
        
The answer is multiplication
