7 inches
Answer:
the coefficient of x is 2
Step-by-step explanation:
(3x - y + z) + (2x - y - z) - (3x - y - z) = 3x - y + z + 2x - y - z - (3x - y - z)
Apply the distributive law: - (a - b) = -a + b
Therefore, - (3x - y - z) = -3x + y + z
So (3x - y + z) + (2x - y - z) - (3x - y - z) = 3x - y + z + 2x - y - z - 3x + y + z
Collect like terms: = 3x + 2x - 3x - y - y + y + z - z + z
Combine like terms: = 2x - y + z
Therefore, the coefficient of x is 2
Therefore, the coefficient of x is 2
The height of the monument is 555 ft and the angle of elevation from the ground is 60°. If d is the distance from a man`s feet to the base of the monument than:
tan 60° = 555 / d
√3 = 555 / d
d = 555 · √3 = 555 · 1.732 = 320.44 ft.
The distance from the man`s feet to the top of the monument is:
320.44 ft · 2 = 640.88 88 ft.
Answer:
The distance from the man`s feet to the base of the monument is 320.44 ft ( just that is correct ).
The domain has infinite solutions, and real number can be the answer. And the range is 2.
