Answer:
The answer is B, 384. Cu cm.
Step-by-step explanation:
This is because you can split this figure into two separate rectangles. The first one has a depth of 2 width of 14 and length of 12 so you multiply L x W which is equal to 168. Then since you want the depth also you multiply 168 x 2 = 336. Next you solve for the last rectangle and add them together. So for this the equation is 2(6 x 4) = 48. 336 + 48 =384.
Hope this helps.
If A and B are equal:
Matrix A must be a diagonal matrix: FALSE.
We only know that A and B are equal, so they can both be non-diagonal matrices. Here's a counterexample:
![A=B=\left[\begin{array}{cc}1&2\\4&5\\7&8\end{array}\right]](https://tex.z-dn.net/?f=A%3DB%3D%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D1%262%5C%5C4%265%5C%5C7%268%5Cend%7Barray%7D%5Cright%5D)
Both matrices must be square: FALSE.
We only know that A and B are equal, so they can both be non-square matrices. The previous counterexample still works
Both matrices must be the same size: TRUE
If A and B are equal, they are literally the same matrix. So, in particular, they also share the size.
For any value of i, j; aij = bij: TRUE
Assuming that there was a small typo in the question, this is also true: two matrices are equal if the correspondent entries are the same.
Answer
the square root of 64 is 8
Explanation
8 x 8 = 64
It is 5/4 if you want it in an improper fraction.
So the rule is multiply down low and add up high.
If you know what 1 (the whole number) times 4 (the denominator) will equal 4
Then add the 1 to the four that will equal 5 with the same denominator which is 4
The answer is 5/4
If that is what you asked
