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:
d₂ = 15 cm
Step-by-step explanation:
The area (A) of a kite is calculated as
A = 
d₁d₂
Here A = 120, d₁ = 16 , then
× 16 × d₂ = 120
8d₂ = 120 ( divide both sides by 8 )
d₂ = 15 cm
Marco is wrong. In order for an input-output table to be a function, there can only be one Y for every X, meaning that X cannot repeat as the same number twice.
