Answer:
Step-by-step explanation:
2x - y + z = 4
4x - 2y + 2z = 8
-x + 3y - z = 5
2x - y + z = 4
-x + 3y - z = 5
x + 2y = 9
4x - 2y + 2z = 8
-2x + 6y - 2z = 10
2x + 4y = 18
x + 2y = 9
2x + 4y = 18
-2x - 4y = -18
2x + 4y = 18
0 =0

0.2 is the answer I believe ^^
Answer:
12.375
Step-by-step explanation:
Length x Width
L x W
4.5*2.75 = 12.375
Simple..
there is a major difference between 6z and

6z means: 6 times z
and

means: z to the power of 6(z*z*z*z*z*z)
An example...
make z=2...plug n chug..
6z----> 6(2)=12
and

--->

=64
As you can see..there is a
major difference.
Thus, your answer.
