If anything is unclear , Please notify me.
I have solved some examples. it's in the picture.
-2xyz(xy + 3yz) = -2x^2 y^2 z - 6x y^2 z^2
Answer:

Step-by-step explanation:
The question is incomplete as the matrix is not given.
The general form of a matrix is:
![b[m*n] =\left[\begin{array}{ccc}b_{11}&b_{12}&b_{13}........b{1n}}\\b_{21}&b_{22}&b_{23}........b{2n}\\b_{31}&b_{32}&b_{33}........b{3n}\\ \\ \\b_{m1}&b_{m2}&b_{m3}........b{mn}\end{array}\right]](https://tex.z-dn.net/?f=b%5Bm%2An%5D%20%3D%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7Db_%7B11%7D%26b_%7B12%7D%26b_%7B13%7D........b%7B1n%7D%7D%5C%5Cb_%7B21%7D%26b_%7B22%7D%26b_%7B23%7D........b%7B2n%7D%5C%5Cb_%7B31%7D%26b_%7B32%7D%26b_%7B33%7D........b%7B3n%7D%5C%5C%20%5C%5C%20%5C%5Cb_%7Bm1%7D%26b_%7Bm2%7D%26b_%7Bm3%7D........b%7Bmn%7D%5Cend%7Barray%7D%5Cright%5D)
Where m and n represent the
respectively.
Notice the position of b11
This means that b11 is at the first column and first row.
Take for instance matrix b is:
![b = \left[\begin{array}{ccc}1&2&3\\4&5&6\\7&8&9\end{array}\right]](https://tex.z-dn.net/?f=b%20%3D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D1%262%263%5C%5C4%265%266%5C%5C7%268%269%5Cend%7Barray%7D%5Cright%5D)
The element at the first row and first column is 1.
Hence

Answer:

Step-by-step explanation:
SOHCAHTOA
O =Opposite
A = Adjacent
H = Hpotenuse
If we draw it out we can see that the opposite side is the UT and adjacent side is SU for ∠S.
When an angle is asked for like here is S so the opposite side of the angle is the opposite side. and the angle close to it is the adjacent. The biggest side is the hypotenuse.
To find the volume of a sphere you would use the equation:
πr³
You would plug in the radius in r
Your equation would look like this now:
π(7)³
When you solve that you would get:
1436
Since it's 3 dimentional you would use ⇒ ³
Your answer would be B. 1436cm³
