 Answer:
the answer is D. 
Step-by-step explanation:
multiply each row in the first matrix by each column in the second matrix.
[4*-2+2*7 4*5+2*-1]
simplify each element of the matrix by multiplying out all the expressions. 
[6 18] 
this matrix is already in the most simplified form.
[6 18]
 
        
             
        
        
        
8 1/2=17/2=8.5
24,700 divided by 8.5=2,905,8823
OR
24,700:17/2  =24,700x2/17=2,905,8823
