As the question is written,
.. f(-1.8) = -2 +8 = 6
We suspect x is missing. Perhaps you intend
.. f(x) = -2x +8
.. f(-1.8) = -2(-1.8) +8 = 11.6
Original height of tree = (x+5) m
In triangle ABC x square = 5 square + 12 square
X square = 25+144
X square = 169
X = 13
Thus the original height of the tree was 13+15 = 18m

Answer:
d =
or d = 5.1
Step-by-step explanation:
![d= \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\d= \sqrt{(-5-0)^2+(-1-(-2))^2}\\d= \sqrt{(-5)^2+(1)^2}\\d= \sqrt{25+1}\\d= \sqrt{26}](https://tex.z-dn.net/?f=d%3D%20%5Csqrt%7B%28x_2-x_1%29%5E2%2B%28y_2-y_1%29%5E2%7D%5C%5Cd%3D%20%5Csqrt%7B%28-5-0%29%5E2%2B%28-1-%28-2%29%29%5E2%7D%5C%5Cd%3D%20%5Csqrt%7B%28-5%29%5E2%2B%281%29%5E2%7D%5C%5Cd%3D%20%5Csqrt%7B25%2B1%7D%5C%5Cd%3D%20%5Csqrt%7B26%7D)
Answer:
75 > x/15
Step-by-step explanation:
Step 1: Mulitply the 15 on both sides in order to get the x by it self.
Step 2: Simplify. 75 x (15) >x/15 x (15)
Step 3: The 15 on the right hand side cancels out leaving the x by itself.
Final Answr: 1125 > x which translates to<em><u> x < 1125</u></em>
