Answer:

2l + 2w = 48

if garden is 15' long

2(15) + 2w = 48 \\ 30 + 2w = 48 \\ 30 - 30 + 2w = 48 - 30 \\ 2w = 18 \\  \frac{2w}{2}  =  \frac{18}{2}  \\ w = 9 \: feet \: wide

mezya [45]

Answer:

f(x) = x^2 - x - 12

Step-by-step explanation:

The function is f(x) = (x + 3)(x - 4), or f(x) = x^2 - x - 12.  Here, a = 1, b = -1, and c = -12.
