Answer: Question #1 The height of the tree is about 18 feet.
To solve this problem, you have to write a proportion using the similar triangles that are drawn. The height of the tree matches the height of the person and the shadows match.
Therefore, we can write and solve the following equation:
x/15 = 5.5/4.5
82.5 = 4.5x
x = 18.33
The solutions are where these two functions intersect, that is, at x = -4 and x = -6. The answer is C.
Answer:
3(x-1)(x+8)
Step-by-step explanation:
3x2+21x−24
3x2+21x−24
=3(x−1)(x+8)
