Which of the following describes the solution to this system of equations

Why "dependent?"

If the system of equations can be shown to have a unique solution, we'd call it "independent."  Have you tried solving this system?  I'd use matrix row operations to do that.

I found that the last row of this 3 by 4 matrix comes out to 0 0 0 0.  This means that the system is DEPENDENT; it does not have a unique solution.

Please review the meaning of "independent" and of "dependent" in this matrix algebra context.

$22. if larry's profit were to minimize by one for every hour his store were to be closed, we would subtract 30 by 8.

The answer would be b ! explanation: the formula for sa *surface area * is 2×l×w+2×l×h+2×w×h so in this case l=4w=12h=8so you use the formula to solve it and it give you the answer of 352^cm^2
