Answer:
Zeroes: ± 6
Step-by-step explanation:
The given polynomial is: 
.
To find the zeroes of the polynomial we equate it to zero.
⇒ 
⇒
⇒ x = -6 and x = +6. They are the zeroes of the polynomial.
Since 
is a quadratic equation it will have two roots. Therefore, the roots are x = -6, -6.
Multiplicity of a root is the number of times the root appears as the solution for the equation.
This makes x = -6 as root with multiplicity two.
Similarly, 
will have three roots.
∴ x = +6, +6 , +6
x = +6 is a root with multiplicity three.
In the above word problem, If she chooses the 8-inch tiles, she will need a quarter as many tiles as she would with 2-inch tiles, Quarter 8-inch tiles will cover the same area as one 2-inches.
<h3>What is the justification for the above?</h3>
Note that the area of the one 2-inch tiles is given as:
A1 = 4in²
The area of the quarter 8-inch tiles is:
A2 = 1/4 x 8 x 8
A2 = 16inch²
Divide both areas
A2/A1= 16/4
= 4
This implies she'll need four 2-inch tiles to cover the same amount of space as a quarter 8-inch tile.

Full Question:
A homeowner is deciding on the size of tiles to use to fully tile a rectangular wall in her bathroom that is 80 inches by 40 inches. The tiles are squares and come in three side lengths: 8 inches, 4 inches, and 2 inches. State if you agree with each statement about the tiles. Explain your reasoning.
If she chooses the 8-inch tiles, she will need a quarter as many tiles as she would with 2-inch tiles,
The angle x is complimentary to the given angle
Therefore x = 90-29 = 61 degrees
For this case we have, by definition, a function is given in the form:
Where x is the independent variable and y is the dependent variable.
If we have:
We can rewrite it in the following way:
Comparing with the generic definition of a function, we have that
Answer:
A relation that could be rewritten using function notation is option b.
