The figure is a parallelogram.
Answer:35 you are welcome
Step-by-step explanation:
A=1x3 means 1 row and 3 columns.
B=3x4 means 3 rows and 4 columns.
AB is a compatible multiplication because A has three columns and B has 3 rows.
However, BA is not a compatible multiplication because B has 4 columns while A has only 1 row.
The general trick is if you read the row/column of the two matrices as 1-3-3-4, and the two middle ones are identical, then AB would be a compatible multiplication. On the other hand, BA would read 3-4-1-3, since 4 and 1 are not identical, so it is not a valid multiplication.
Do remember 1x3 means 1 ROW and 3 COLUMNS.
Answer:
A is the answer
Step-by-step explanation:
(0, -5):
-5 = 2(0) - 5 >>> -5 = -5
-5 = (0)^2 - 5 >>> -5 = -5
(2, -1):
-1 = 2(2) - 5 >>> -1 = 4 - 5 >>> -1 = -1
-1 = (2)^2 - 5 >>> -1 = 4 - 5 >>> -1 = -1
