1)8
2)3
3)1
4)14
the coefficient is the number in front of the variable
Answer:
A) x = 8
Step-by-step explanation:
in a 45-45-90 triangle, the legs to hypotenuse ratio is 1 : 
so in this problem the leg is 8 and the hypotenuse is 8
21) 3(2j-k)=108 It is asking you to set the equation equal to j
distribute the 3
6j-3k=108
move k to the other side by adding on both sides
6j=108+3k
divide everything by 6
j=18+0.5k
Answer:yes
Step-by-step explanation:
Answer:
Not possible.
Step-by-step explanation:
Addition of Matrix A and Matrix B is possible only if the order of matrix A is same as the order of matrix B.
Order of a matrix with
rows and
columns is
.
Here, matrix A is ![\left[\begin{array}{ccc}2&-4\\-4&10\\0&-8\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D2%26-4%5C%5C-4%2610%5C%5C0%26-8%5Cend%7Barray%7D%5Cright%5D)
Matrix B is
.
Multiplying a matrix by a constant doesn't change its order.
So, order of matrix A is
as it has 3 rows and 2 columns.
The order of matrix 3B is
as it has 2 rows and 3 columns.
Therefore, addition is not possible as the order is different.
