a. 2x + 11
b . −3x² − 2x + 11
c . 4x³ − 3x² − 2x + 11
d . 5x⁴ + 4x³ − 3x² − 2x + 11
<h3>What is an expression?</h3>
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
The polynomial having a degree of three is called the cubic polynomial which means that the maximum power of the polynomial will be three and the solutions will also be three.
Here in the option, we can see that the maximum power of the polynomial is three and it will have a maximum of three solutions.
The third-degree expression will be:-
E = 4x³ − 3x² − 2x + 11
Therefore the correct answer is Option c which is the cubic expression is 4x³ − 3x² − 2x + 11

Answer:
$15
Step-by-step explanation:
The original price of the mirror is unknown, so let's call it x.
The discount on the original price is a 20% discount, so it is 20% of x, or 0.2x.
We are told the discount is $3, so 0.2x = 3. Now we solve the equation for x.
0.2x = 3
Divide both sides by 0.2.
x = 3/0.2
x = 15
The regular price is $15.
