Question

PLEASE HELP! Will become fan. And give medal.

16. The area of a rectangular table is given by the trinomial x2 + 7x – 30. What are the possible dimensions of the rectangle? Use factoring. (1 point)
a. (x+10) and (x-3)
b. (x-10) and (x-3)
c. (x+10) and (x+3)
d. (x-10) and (x+3)

Answer 1

@agent0smith can you help at all? :/

Answer 2

\[\huge x^2 + 7x – 30= x^2 + 10x-3x – 30\]
\[\huge = x(x + 10)-3(x +10) = (x+10) (x-3) \]
Hence option a. (x+10) (x-3) are the required dimensions of the rectangle.
