305 divided by 12.2 equals 25. Have a nice day! ^ U ^
Let's rewrite the expression as
So, if 
, you may divide both sides by 
, the equation becomes 
, and the only solution is 
, which means that this is not an identity (an indentity is tautologically true, no matter the value of x).
If instead 
, you are multiplying both sides by zero, so the equation becomes
So, it doesn't matter which value for x you choose, because you will always end up with 
, which is obviously always true.
Answer:
false
Step-by-step explanation:
![\left[\begin{array}{c}-4\end{array}\right] +\left[\begin{array}{c}7\end{array}\right] =\left[\begin{array}{c}3\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bc%7D-4%5Cend%7Barray%7D%5Cright%5D%20%2B%5Cleft%5B%5Cbegin%7Barray%7D%7Bc%7D7%5Cend%7Barray%7D%5Cright%5D%20%3D%5Cleft%5B%5Cbegin%7Barray%7D%7Bc%7D3%5Cend%7Barray%7D%5Cright%5D)
Both of the matrices are 1 x 1 ("one by one"), so they can be added to produce a 1 x 1 matrix.
To add (or subtract) two matrices, they must be the same size.
(m x n) + (m x n) = (m x n)
m x n means a matrix has m rows and n columns. Dimensions are always named in that order: rows, then columns.
Question:
If all the edges of prism A are multiplied by 5 to create prism B. The volume of prism B will be __________ times the volume of prism A?
* 5
* 125
* 50
* 25
Answer:
* 5 times.
Step-by-step explanation:
Let us represent all the edges of prism A as = X
Prism B = All the edges of Prism A × 5
Prism B = X × 5
= 5X
Let's assume the prism is a cube
Volume of a Prism(cube) = L × W × H
Volume of Prism A = L × W × H
Volume of Prism B = 5 (L × W × H)
Therefore, The volume of prism B will be 5 times the volume of prism A
