Answer:
(2,6)
Step-by-step explanation:
x-y=-4 -----> Get the one of the variables by themselves
x=-4+y -----> All i did was adding the y to the the other side to get x by itself
Now all you do is to substitute the in the equation into the other equation
x=-4+y --------------> 6(-4+y)-4y=-12
Then solve
Now since you have your y now all you need to do is to do the same thing
Substitute the y in for the other equation
Then there you go

Step-by-step explanation:
The question is incomplete, as the options to select the required condition from were not listed. So, I will answer on general terms
From the question, we understand that the cube has an open-top and the surface ares is 256 in^2
Let L represents the edge length, the surface area (S) is:

Substitute 256 for S

Divide both sides by 5

Take square roots of both sides:


---- approximated
The volume of the cube is:




<em>So, the edge length of the cube is 7.16 inches and the volume is 366.36 cubic inches</em>

11x=1
x= 1/11 (divide 11 on both side)
