Polynomials are linear combinations of positive integer powers. For example,
is a polynomial, but
is not.
(In case you're unfamiliar with the term, a linear combination of two quantities is the sum of scaled versions of those quantities, e.g. a general linear combination of 
and 
is 
, where 
are any numbers.)
is not a polynomial; the offending term is

Answer: Let the Number of hours Enzo sleeps on average per day while School is in session be Y
Y = SS/115% = SS/1.15
Step-by-step explanation:
Given in the question:
- While on vacation, Enzo sleeps 115% as much as he sleeps when school is in session.
- Enzo sleeps SS hours per day during vacation
Mathematically, SS = 115% of Y
SS = 115% × Y
115% × Y = SS
Y = SS/115%
But 115% = 115/100 = 1.15
Therefore,
Y = SS/1.15

You can find the area of this figure by finding the area of the square and then the area of the triangle. Once you find these 2 areas then add them together.
For the area of the square:
A= b x h
A = 4 cm x 6 cm
A = 24 cm²
For the area of the triangle:
A = b x h/2
A = 3 cm x 6 cm/2
A = 9 cm²
Total area = 24 cm² + 9cm²
Total area = 33 cm²
