Answer:
15840 feet
Step-by-step explanation:
There are 5280 feet in a mile.
5280 * 3 = 15840 feet
The x-intercept of f(x) = (x + 6)(x - 3)
f(x) = 0 → (x + 6)(x - 3) = 0 → x + 6 =0 or x - 3 =0
x = -6 or x = 3
Therefore the x-intercepts are: (-6; 0) and (3; 0)
Your answer is (-6; 0)
So the answer might be 61.0 because if you subtract (-)63.5 with 2.5 it would 61.0 so i dont know ..but good luck and if i fail you im so sorry
