Answer:
Option A is correct.
Step-by-step explanation:
We need to find the difference of two matrices.
The matrices are:
![\left[\begin{array}{cc}-4&8\\3&12\end{array}\right] - \left[\begin{array}{cc}2&1\\-14&15\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D-4%268%5C%5C3%2612%5Cend%7Barray%7D%5Cright%5D%20-%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D2%261%5C%5C-14%2615%5Cend%7Barray%7D%5Cright%5D)
We will subtract each row entry of Matrix 1 from the corresponding row entry of Matrix 2.
![\left[\begin{array}{cc}-4-2&8-1\\3+14&12-15\end{array}\right]\\\left[\begin{array}{cc}-6&7\\17&-3\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D-4-2%268-1%5C%5C3%2B14%2612-15%5Cend%7Barray%7D%5Cright%5D%5C%5C%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D-6%267%5C%5C17%26-3%5Cend%7Barray%7D%5Cright%5D)
So, We get the answer
![\left[\begin{array}{cc}-6&7\\17&-3\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D-6%267%5C%5C17%26-3%5Cend%7Barray%7D%5Cright%5D)
which matches Option A.
So, Option A is correct.
Answer:
The answer is B hope i'm right i'm 99 percent sure i am.
A + 5x + 2 means . . .
a can be any number
5 is multipled by x
x can be any number
2 stays the same
So it would be . . .
a + 5x + 2
An example of this is a would be 6 and x would be 2 so it would be written as . . .
6 + 5(2) + 2 = 18.
Hope this helps
And have a NICE DAY .... :) :D
Also pick me as the brainiest answer/crown :)
Life probably stayed the same because a farm is big and usually cities are big too. The difference is that a city is VERY loud. especially at night. A farm is very quiet.
