This is a polynomial.
Step-by-step explanation:
A monomial is a constant, a variable or the product of constants and variables.
A binomial is the sum or difference of two monomials.
A trinomial is the sum or difference of three monomials.
Anything more than three terms makes it a polynomial.
This has 4 terms; thus it is a polynomial.
Answer:
They subtracted the values incorrectly
Step-by-step explanation:
The formula for finding the distance between two points is this:

The person subtracted the variables incorrectly and subtracted x1 from x2 and y1 from y2 instead of the other way around.
To correctly solve it, do this:

3+7 = 10
You do 500/10 which is 50 to find out 1
1 = 50
3 = 50 x 3 = 150
7 = 50 x 7 = 350
The ratio is 150 : 350
