We can use a theorem called Proportional segments in right triangles.
1. How far is library from the park?
<span>
The perpendicular is the mean proportional between the segments of the hypotenuse, so:
</span>

2. How far is the park from the football field?
<span>
Each leg of the given triangle is the mean proportional between the hypotenuse and the adjacent segment, so:
</span>

Answer: A.
Sean is correct, because he adds 0 to -100, which equals to -100
<em />I dont think Candice is correct however, since you cannot repeat the numbers
(and adding negative numbers is incorrect im assuming)
hope this helps
Answer:-2
Step-by-step explanation:
(n + 3) 5 = 3 x 1 - n
distribute so 5n + 15= 3 - n
subtract three from both sides
5n - 12 = -n
subtract 5n from both sides
12 = −6n
Divide both sides by -6
n=-2
Add all the like terms
3b + b = b(3 + 1) = 4b
So, 3b + b + 6 = 4b + 6
