Let A and E be matrices with the following sizes.
A: 3 × 2 E: 2 × 3
If defined, determine the size of the matrix
E − 2A.

(If an answer is undefined, enter UNDEFINED.)
[ ] x [ ]

If not defined, explain why.

a. E − 2A is defined
b. E − 2A is not defined because E and 2A have different sizes.
c. E − 2A is not defined because E and 2A have the same size.
d. E − 2A is not defined because the number of columns of E does not equal the number of rows of 2A.
e. E − 2A is not defined because the number of rows of E does not equal the number of columns of 2A.
