is a monomial (since it is all connected by multiplication) and since it is in the degree of 2, that makes it a quadratic.
-2 is a constant (since it doesn't have variables) and it is a monomial (since it is all connected by multiplication)
3x-9 is a binomial (since it has two terms, not connected by multiplication) and since it has x in the power of 1, that makes it a linear equation.
Finally,

-6x + 9 is a trinomial (since it has 3 terms connected by either addition or subtraction) and since the degree of the polynomial is 2, that makes it a quadratic.
Answer:
17.5
Step-by-step explanation:
Petra can make 8 costumes with 12 yards of fabric
<h3><u>Solution:</u></h3>
Given that Petra was given 12 yards of fabric to make costumes for the school play
Each costume requires
yards
<em><u>To find: number of costume Petra can make</u></em>
The number of costume Petra can make is calculated by dividing the total fabric she has by fabric needed for one costume

Total fabric she has = 12 yards
Fabric needed for 1 costume =
yards
Therefore,

Thus petra can make 8 costumes with 12 yards of fabric
Answer:
The person's height must be greater than or equal to 55 inches to go on the ride
Step-by-step explanation:
Let
x -----> the height of the person
we know that
A person must be at least 55 inches tall to go on the carnival ride
The phrase " at least" means "greater than or equal to"
so
The inequality that represent this situation is

therefore
The person's height must be greater than or equal to 55 inches to go on the ride
