The area of a rectangular painting is given by the trinomial x2 – 5x – 36. What are the possible dimensions of the painting? Use factoring.
A. (x + 9) and (x – 4)
B. (x + 9) and (x + 4)
C. (x – 9) and (x – 4)
D. (x – 9) and (x + 4)
The trinomial x² - 5x - 36 can be factored as (x - 9)(x + 4). This means that the possible dimensions of the painting are (x - 9) and (x + 4). The correct answer is D.
To find the possible dimensions of the painting, we need to factor the trinomial x^2 - 5x - 36.
The factored form of the trinomial is (x + 9)(x - 4).
This means that the possible dimensions of the painting are (x + 9) and (x - 4).
Therefore, the correct answer is A. (x + 9) and (x - 4).
