Simplification form of the provided expression is -x⁴-2x³+2x+5 option (B) is correct.
<h3>What is an expression?</h3>
It is defined as the combination of constants and variables with mathematical operators.
The options are:
A) -x⁴ - 2x - x + 2
B) -x⁴ - 2x³ + 2x + 5
C) -2x³ + 1
D) -x - 2x² + 2x + 5
We have an expression:
= (x + 3) - [(x + 2)(x³ - 1)]
Thus, simplification form of the provided expression is -x⁴-2x³+2x+5 option (B) is correct.

Answer:
405 Problems
Step-by-step explanation:
- One student in class has 15 problems.
- There are 27 students in the class.
Let's <u>multiply</u> 15 by 27.
<em>In all, there would be 405 problems assigned to the whole class.</em>
The answer for the problems are below in the picture let me know if that makes sense.
x is equal to - 2/3 after collecting like terms
The statement "unit cubes with side lengths of 1/2 foot are added to fill the prism with no space remaining" is useless information so you can disregard that. All you need to know to calculate the volume is the length, width, and height.
Volume = length x width x height
Volume = (5/2) x 3 x 11/2
Volume = 15/2 x 11/2
Volume = 165/4
Volume = 41.25 ft cubed
