seven And here the potential And before we spoil the
- 00:25
ending hit pause it right there All right so this
- 00:30
is just testing whether we understand absolute values and that
- 00:33
we can be surgically careful in the numbers were plugging
- 00:36
into a place The variables In this case we just
- 00:40
rewrite the bass problem and we have the absolute value
- 00:43
of negative five plus positive seven which is positive too
- 00:46
And yet here the absolute value provides really doesn't matter
- 00:49
Plug in the other side and we have the absolute
- 00:52
values a or negative five which is positive Five and
- 00:55
absolute value Land and envy is seven and they're total
- 00:59
is twelve so we have two is less than equal
- 01:02
to or greater than twelve Well who is less than
- 01:06
twelve Not a toughie here So the answer is a
- 01:08
done Looks like this problem is strictly out patient yeah
