Answer:
It is wrong
Step-by-step explanation:
y < 18
This is read as y is less than 18. If the students forgot to flip the symbol and mistakenly believe that y > 18.
y > 18
This is read as y is greater than 18.
There is a difference between the numbers greater or less than 18 .
y must have numbers less than 18 and 21 is greater than 18.
Therefore it is wrong.
But to make it true we can multiply minus with the inequality y > 18
-y > -18
This reverses the inequality sign and it becomes
y< 18
The solution which is required.

Answer:
5xy^2(y + 3x^2 - 6x).
Step-by-step explanation:
5xy^3 + 15x^3y^2 − 30x^2y^2
The GCF is 5xy^2 so dividing through by this we get the factors:
= 5xy^2(y + 3x^2 - 6x).
