The area of a rectangular table is given by the trinomial x^2 + 7x - 30. What are the possible dimensions of the rectangle? Use factoring.
(1 point)
A. (5x + 7) and (-x - 2)
B. (5x + 7) and (x - 2)
C. (5x - 7) and (x - 2)
D. (5x - 7) and (x + 2)
To find the possible dimensions of the rectangle, we need to factor the trinomial x^2 + 7x - 30.
The factored form of the trinomial is (x + 10)(x - 3).
Since the dimensions of a rectangle cannot be negative, we can ignore the factor (x + 10).
The possible dimensions of the rectangle are (x - 3) and (x + 10).
Therefore, the correct answer is B. (5x + 7) and (x - 2).
