Question

The area of a rectangular garden is given by the trinomial x2 + 6x – 27. What are the possible dimensions of the rectangle? Use factoring.

Answer 1

A = x^2 + 6x - 27
A = x^2 + 9x - 3x - 27
A = x(x+9)-3(x+9)
A = (x+9)(x-3)
A = lw

l = (x+9)
w =(x-3)

Answer 2

True, but your math is off. It would actually be L=(x+10), W=(x-3). but you r process was correct.
