These matrices ARE inverses of each other!
Addition and multiplication are commutative property so that mean no.
In this case, you have to do division.
Your answer is 6x = 72
x = 12
Hope this helps :)
Answer:
72 cm³ (see below)
Step-by-step explanation:
First, refer to the volume formula:
V = l · w · h
If you plug in all of your values and simplify, you'll get the volume:
l = 6 cm
w = 3 cm
h = 4 cm
V = (6) (3) (4)
V = 18 (4)
V = 72 cm³
Because this is volume, the measurements are units cubed, meaning it's cm³.
2/3 x4 = 8/12
therefore,
They will need 8/12 cup oil
The expression is 9*

+2+

.
9*

+2+

---> First square

by squaring the top and bottom number.
=9*

+2+

---> Multiply 9 and

=1+2+

---> Add
=3

---> Optional: turn into improper fraction
