Answer:
x=-3,5
Step-by-step explanation:
F(x)=-4x-1 if you sub 3 into it you get 3(-4)-1 which is -13 and 2x+4=10
You would have to find the proportionality of the two. If his shadow is 3 feet long, and the tree's shadow is 9 that means it is proportioned by 3. So the height of the tree would be 15.
Answer:
35+13-36
Step-by-step explanation:
35+13=48
48-36=12
Answer: 60
Step-by-step explanation:
If the entire blue length is 100 and one of the parts of that is 64, the other part is 36.
So by the geometric mean theorem, letting the length of the dotted altitude be y,

So if y=48, by the Pythagorean
theorem,
