Answer:
The domain is all of the x values. From the graph, all of the x values are greater than or equal to 0 so the answer is x ≥ 0.
Answer:
−2x−8y−4z
Hope this is what you wanted :)
Isn't the only thing you have to do is since a cube has 6 sides than you would have to do 150 divided by 6. If I am correct.
Answer:
7 feet
Step-by-step explanation:
Length of one piece of string = 28 feet.
Length of the second string = 42 feet.
Since the number of required pieces was not given but many are required, the greatest length can be determined by;
If the maximum length is 7 feet, then:
the number of pieces from 28 feet long string = 
= 4
Also,
the number of pieces from the 42 feet lone string = 
= 6
Total number of 7 feet strings that she can make = 4 + 6
= 10
Since many pieces are required, the greatest length she can make is 7 feet. If she increase the length to 14 feet, the number of pieces would be 5 which limit the required number.
Simple....
you have:

So...first you know you're trying to find x..
But, you have a square root on one side...to remove this you'd have to square both sides--->>>

Leaving you with....

Move the terms over and set it equal to
zero.
-->>

Factor out a 3...

What multiplies to -12 and adds to 4?
6*-2=-12
6+-2=4
Leaving you with...

Remember you're solving for 0....
3x-2=0
3x-2=0
+2 +2
3x=2

x=
Then-->>
x+2=0
x+2=0
-2 -2
x=-2
Thus, your answer.
