Hey :)
First, find the GCF.
It is 6 since it divides evenly into 42x and -18.

Second, factor out the gcf and divide each term by the GCF.
6(42x/6 - 18/6)

Lastly simplify.
6(7x-3)

There are many different ways to do it and that's one of them.

Hope this helps !!
Good luck:)

Pepsi [2]

So to find out the answer, you need to find out the dimensions of each cube. So for the 1331, it's 11 x 11 x 11. So you know that would be 11 meters high. Now the next cube. Then there's another 1331, so that would be another 11 meters high. Then 729, also 9 x 9 x 9, so that's going to be 9 meters high. Then add all the cube square roots. 11 + 11 + 9 = 31. So the height of the stacked boxes will be 31 meters.
