Step-by-step explanation:
Answer:
(x - 9)(x + 8)
Step-by-step explanation:
Given
x² - x - 72
Consider the factors of the constant term (- 72) which sum to give the coefficient of the x- term (- 1)
the factors are - 9 and + 8, since
- 9 × 8 = - 72 and - 9 + 8 = - 1, thus
x² - x - 72 = (x - 9)(x + 8)

Answer:
5507.79 feet
Step-by-step explanation:
To find the height of the mountain, we can draw triangles as in the image attached.
Let's call the height of the mountain 'h', and the distance from the first point (31 degrees) to the mountain 'x'.
Then, we can use the tangent relation of the angles:
tan(34) = h/x
tan(31) = h/(x+1000)
tan(31) is equal to 0.6009, and tan(34) is equal to 0.6745, so:
h/x = 0.6745 -> x = h/0.6745
using this value of x in the second equation:
h/(x+1000) = 0.6009
h/(h/0.6745 + 1000) = 0.6009
h = 0.6009 * (h/0.6745 + 1000)
h = 0.8909*h + 600.9
0.1091h = 600.9
h = 600.9 / 0.1091 = 5507.79 feet
