The statement is FALSE.
A constant term is also a polynomial with just one term and degree 0. The degree of the polynomial can be any non-zero integer i.e. can be 0 or greater than zero.
So the correct statement will be:
An expression must have a monomial of degree 0 or higher to be a polynomial
Answer:
The domain is all real numbers
-inf<x<inf
Answer:
l = 
Step-by-step explanation:
Given
P = 2(l + w) ← distribute right side
P = 2l + 2w ( subtract 2w from both sides )
P - 2w = 2l ( isolate l by dividing both sides by 2 )
= l
