√196

my answer:
8²*3=64*3=196
√64*√3=√8*√8*√3-reduce
=√4*√4*√3-reduce
=√2*√2*√3

=4√3
The correct anwser is 8√3
Nopte: 8² is a perfect square of finding squaroots.

Why is my anwser wrong?

A small company produces both standard and deluxe playhouses. The standard playhouses take 12 hours of labor to produce, and the deluxe playhouses take 20 hours. The labor available is limited to 800 hours per week, and the total production capacity is 50 items per week. Existing orders require the company to produce at least 10 standard playhouses and 15 deluxe playhouses per week. Write a system of inequalities representing this situation, where x is the number of standard playhouses and y is the number of deluxe playhouses. Then graph the system of inequalities below.

This thing has my dad and I baffled: we can't figure out what its for. It looks like a compass with one of its legs missing. On its end you can see it has a detachable piece, which has what appears to be a pencil eraser on it.

On its circular edge degrees are marked out. The 100 degree mark is specifically marked by a metal notch, and there appears to be an inner circle that you can rotate to select degrees or something.

Any help you guys can give would be appreciated!

Why could this be? A waste of time waiting around.

Do they NOT like to do these in assault cases in case they have to testify?

Or was it because my signs and symptoms were not severe enough? Your guess unless you have insider information.

Is the cut material actually jaggedly "torn" along molecule boundaries or are molecules levered aside? What are the sources of heat generated by cutting?
