Find the area of the rectangle below: 3x3 −4x3 +5 (1 point) Responses 12x6−15x3 12 x to the 6th power minus 15 x cubed −12x9+15x3 negative 12 x to the 9th power plus 15 x cubed −12x6+15x3 negative 12 x to the 6th power plus 15 x cubed −x3+5 negative x cubed plus 5 11x3−2

Answer 1

To find the area of the rectangle defined by the expression \( 3x^3 - 4x^3 + 5 \), we first need to simplify the expression:

1. Combine like terms: \[ 3x^3 - 4x^3 = -1x^3 \] So, the expression simplifies to: \[ -x^3 + 5 \]

Now, if we assume that the area of the rectangle is represented by the expression \( -x^3 + 5 \), we would typically evaluate it at specific values of \( x \) to find the area. Without specific values or dimensions for the rectangle, we can only express the area in terms of \( x \).

However, if the goal is to simply identify a corresponding answer from the provided options based on simplifying the initial expression \( 3x^3 - 4x^3 + 5 \), the correct simplification matches the answer:

\[ -x^3 + 5 \]

Therefore, the correct answer is:

-x^3 + 5.
