Answer:
Distributive Property
Step-by-step explanation:
In this property a(b + c) = ab+ac; what's going on in your example is similar; the 3x is being distributed to 4 and 5.
Answer:
Step-by-step explanation:
You can only multiply matrices if the number of columns in the matrix on the left is the same exact number as the number of rows in the matrix to the right of that other matrix.
The matrix on the left, |5 -2 4| has the dimensions
1 x 3 (1 row, 3 columns)
The matrix to its right, |2 7 -3| has the dimensions
1 x 3 (1 row, 3 columns).
Putting those dimensions next to each other in that order:
1 x 3 1 x 3
The bold print 3 and 1 have to be the same number (both 3's or both 1's) in order for the multiplication to work. This doesn't work; it's impossible.
