An expression must have a monomial of degree 2 or higher to be a polynomial.

a. true
b. false

True - depends on context

Step-by-step explanation:

Polynomial means "many terms' and must have 2 or more terms which includes binomials. If this is true, then the expression is false because x+2 is a polynomial specifically binomial without degree 2. This is because we applied the definition of a polynomial loosely.

However, in terms of functions and with s stricter definition then polynomials are expressions with degree 2 or higher usually with 3 or more terms. Then it is true.

The statement in Python is:

print("The average pH of citrus fruits is ",avg_citrus_pH)

Java

System.out.print("The average pH of citrus fruits is "+avg_citrus_pH);

C++

cout<<"The average pH of citrus fruits is "<<avg_citrus_pH;

Explanation:

The programming language is not stated; so, I answered the question in 3 languages (Python, Java and C++)

Assume that avg_citrus_pH has been declared and initialized; all you need to do is invoke a print statement and then append the variable

In Python, use print()

In c++, use cout<<

In Java, use System.out.print()

So, the statements are:

Python:

print("The average pH of citrus fruits is ",avg_citrus_pH)

Java

System.out.print("The average pH of citrus fruits is "+avg_citrus_pH);

C++

cout<<"The average pH of citrus fruits is "<<avg_citrus_pH;
