If A=[(-3,1,6),(2,-5,0),(1,-3,4)],B=[(4,...

If `A=[(-3,1,6),(2,-5,0),(1,-3,4)],B=[(4,7),(-4,2),(-1,-5)]` and AX=B, then the size of X is

A

3 rows, 3 columns

B

3 rows, 2 columns

C

2 rows, 2 columns

D

2 rows, 3 columns

Text Solution

Verified by Experts

The correct Answer is:
B
X must have as many rows as A has columns, which 3. X must have as many columns as B does, which is 2.
