He may be wrong. If he was wrong, this is the example.
0 < -10x
If we were to divide both sides by -10, even though the answer would be undefined or just end up as zero, it is just a common rule to always flip the sign whenever you divide or multiply by a negative.
Don't quote me on it, but I think I'm right.
Hope this helped!

Answer:
36.4 m
Step-by-step explanation:
Rounded to tenths, the dimensions are ...
12.7 m by 5.5 m
The sum of these is 18.2 m, so the estimate of the perimeter is ...
2·18.2 = 36.4 m
_____
The perimeter formula is ...
P = 2(L +W) . . . . . twice the sum of length and width.
Answer:
Consider points (-1, 0) and (0, 1) :
If set A shows the statistians and B shows the person who bath regularly then the notation which shows that all statistians bath regularly is A∩B.
Given that A shows the statistians and B shows the person who bath regularly.
We are required to show the sentence that "All statistians bath regularly"in set notation.
We know that set is a collection of things, place,anything which can be measured or denoted as something else.
"∪" shows union means when we put this sign between two sets then the resulting set will contain all the elements of both the sets.
"∩" shows intersection means when we put this sign between two sets then the resulting set will contain all the common elements of both the sets.
Since A represents statistians and B represents people who bath regularly and we require statistians who bath regularly is A∩B.
Hence if A shows the statistians and B shows the person who bath regularly then the notation which shows that all statistians bath regularly is A∩B.
