Hi, Kaylasole99! :)
11.25*28%
=$3.15
11.25-3.15
=$8.10
With taxes deducted, Henry makes $8.10 an hour.
To find how many hours he needs to work to make $324, we can create an equation:
Solve for x.
Divide both sides by 8.10.
Simplify.
It would take Henry 40 hours in order to make $324.
Hope this helps.

Answer: a) AB = ; b)
; c) No, they are different; d) No, they are never the same;

. 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
