The rule to check if a triplet of numbers can represent the sides of a triangle is the following: the sum of the length of two sides must exceed the third one.
This happens for all possible couples in your case:



2x^(3)y+7xy-3x^(2)-12y
is in standard form
The slope is 3/4. you need to find the change of y over the change of x.
Answer:
27.8%
Step-by-step explanation:

The % reduction is:
(100-72.2)% = 27.8%
