Answer:
Element wise subtraction.
Step-by-step explanation:
Matrix Subtraction is done element wise.
Therefore, D = ![\[ \left[ {\begin{array}{ccc} 3 & 1 & 0 \\ -1 & 2 & 4 \\9 & 7 & -2 \end{array} } \right]\]](https://tex.z-dn.net/?f=%5C%5B%20%20%5Cleft%5B%20%7B%5Cbegin%7Barray%7D%7Bccc%7D%20%20%203%20%26%201%20%26%200%20%5C%5C%20%20%20-1%20%26%202%20%26%204%20%5C%5C9%20%26%207%20%26%20-2%20%20%5Cend%7Barray%7D%20%7D%20%5Cright%5D%5C%5D)
- ![\[ \left[ {\begin{array}{ccc} 5 & 2 & -4\\ 1 & 12 & 3 \\ 11 & 3 & -2 \end{array} } \right]\]](https://tex.z-dn.net/?f=%5C%5B%20%20%5Cleft%5B%20%7B%5Cbegin%7Barray%7D%7Bccc%7D%20%20%205%20%26%202%20%26%20-4%5C%5C%20%20%201%20%26%2012%20%26%203%20%5C%5C%2011%20%26%203%20%26%20-2%20%20%5Cend%7Barray%7D%20%7D%20%5Cright%5D%5C%5D)
This becomes:

Now, 
Answer:
c
Step-by-step explanation:
You can find that 22-6=38-22=54-38=70-54=16
so the answer is c 16
log was used calculate big numbers before calculators
log is a re-arranged way to show a number with an exponent
example
log₂ 16 = 4 means 2^4 = 16
logx(Z) = y means x^y=Z
log(x-6)/log(2) + log(x)/log(2) = 4
(log(x-6)+ log(x))/log(2) = 4
(log(x-6)+ log(x)) = 4log(2)
(log(x-6)x) = log(16)
x=8
