<span>Checking the existence conditions for the multiplication of matrices, the following properties are valid:
1- associative: </span>
<span>
2- distributive in relation to addition: </span>
<span>
3- neutral element: </span>
, where
is the identity matrix of order
p.s:.
For the multiplication of matrices is not worth the commutative property.
Therefore:
Answer <span>B) It satisfies the associative and distributive properties, but not the commutative property.</span>
Answer:
5+5=10 24+12=36^3 = 46,656
Step-by-step explanation:
So will start off with the Left Side which begins with 5+5= 10
Right Side (24+12)3 So we will add what is in the Parantheses 24+12=36
36^3 is 46,656
-x+4(x+3) = 9
Multiplying...
-x+4x+12=9
So,
3x + 12 = 9
Now, subtract 12 from both sides.
3x + 12 - 12 = 9 - 12
3x = -3
Then, divide by 3.
3x/3 = -3/3
x = -1
