Answer:
-4x³ + 9x² + 2x + 24
Explanation:
To find how much great is the volume of the larger rectangular prism than the smaller prism, we need to subtract
Volume of larger rectangular prism - Volume of smaller prism =
= x³ + 3x² - 4x + 7 - (5x³ - 6x² - 6x - 17)
To remove the parenthesis,multiply each term of the smaller prism by (-1)
= x³ + 3x²- 4x + 7 - 5x³ + 6x² + 6x + 17
= x³ -5x³ + 3x² + 6x² - 4x + 6x +7 + 17 {Combine like terms}
= -4x³ + 9x² + 2x + 24
