Answer:

The third choice: (x² - 1)³

Step-by-step explanation:

That is the only expression that is a binomial. Binomial means "two numbers". For this expression, x² is one number, and -1 is the other. Choice 1 is a monomial (one number) and choices 2 and 4 are trinomials (three numbers)

Price of one adult ticket is $9 and price of one student ticket is also $9.

Step-by-step explanation:

Let,

Adult ticket = x

Student ticket = y

According to given statement;

x+2y=27 Eqn 1

2x+2y=36 Eqn 2

Subtracting Eqn 1 from Eqn 2;

$(2x+2y)-(x+2y)=36-27\\2x+2y-x-2y=9\\x=9$

Putting x=9 in Eqn 1;

$9+2y=27\\2y=27-9\\2y=18$

Dividing both sides by 2;

$\frac{2y}{2}=\frac{18}{2}\\y=9$

Price of one adult ticket is $9 and price of one student ticket is also $9.
