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. (x + 10) and (x - 3)
B. (x - 9) and (x - 3)
C. (x + 9) and (x + 3)
D. (x - 9) and (x + 3)
To find the dimensions of the rectangle, we need to factor the trinomial x^2 + 7x - 30.
The factors of -30 that can be combined to give 7 are 10 and -3.
Therefore, the factored form of the trinomial is (x + 10)(x - 3).
The possible dimensions of the rectangle are (x + 10) and (x - 3).
So, the answer is:
A. (x + 10) and (x - 3)
