Step-by-step explanation: Both 64 and x^2 are perfect squares, since 64=(8)^2 and x^2=(x)^2. Additionally, 16x is twice the product of the roots of 64 and x^2, since 16x=2(8)(x). So the side length of the square is 8-x meters
I think I don’t exactly remember don’t judge me
Answer: a) AB = ; b) ; c) No, they are different; d) No, they are never the same;
Step-by-step explanation:
a) A = , B = . This multiplication is possible, because matrix A has 2 columns and matrix B has 2 rows. When those value are equal, the multiplication is possible.
AB = . =
b) BA = . =
c) As, we can see, parts a and b are differents.
d) With matrices, multiplication is not commutative, which means AB≠BA
