Answer:
det(A)=-det(B)
Step-by-step explanation:
We have two matrices A, and B.
Matrix B is obtained by swapping rows 1 and 3 of matrix A.
Whenever we swap rows in matrices, the determinants does not change but the sign changes.
Therefore
det(A)=-det(B)
Also no two rows of of both matrices are the same, therefore
det(A)≠0, and det(B)≠0
Answer:
X/3 because you need to divide Tylers books (x) by 3.
Step-by-step explanation:
If Tyler has 3 times as many books as Mai then you would need to divide Tyler's amount of books by 3.
Answer:
-121/336
Step-by-step explanation:
The lateral surface area is the surface area of the cube excluding the base and the top, which would make 4 square planes.
First we can find the area of a square plane:
4 1/2 x 4 1//2
=20 1/4 ft²
We can then multiply the area of plane by 4:
20 1/4 x 4
=81 ft²
Therefore the answer is 81 ft².
Hope it helps!
