To multiply B and A, the number of columns of B must matc the number of rows of A.
<h3>
When we can multiply two matrices?</h3>
When we multiply two matrices, A and B, we multiply the rows of matrix A by the columns of matrix B.
Now, the number of elements in a row of a matrix, is equal to the number of columns (and the number of elements in a column is equal to the number of rows).
To multiply BxA:
Then, a row on matrix B must have the same number of elements than a column in row A.
Then, to multiply BxA, the number of columns of B must match the number of rows of A, meaning that the correct option is the last one.

Answer:
10,477.1(429) kg/m³
Step-by-step explanation:
The basic formula for density is M/V, or mass divided by volume.
The given mass is 73,340 and the volume is 7.
73,340 is 10,477.1429 (which rounds to 10,477.1)
Therefore, the density is 10,477.1 kg/m³
My English is not that great but if I got it right the answer is 3
36/99 because 36 divided by 99 is 0.363636363636
The answer is A, y = -2x + 3. This stuff is easy you should learn it
