ANSWER
EXPLANATION
The diameter meets the tangent to the circle at right angles.
The sum of interior angles of a triangle is 180°.
This implies that
Group the constant terms
We simplify to obtain,
For both problems, we can use the section formula.
1) 
2) 
Given :
A freight elevator has a weight limit of 15,000 pounds.
Workers have loaded items weighing 2.6 tons onto the elevator.
To Find :
How many more pounds of freight can they load before reaching the weight limit.
Solution :
We know, 1 ton = 2000 pounds.
So, 2.6 ton = 2.6 × 2000 = 5200 pounds.
Now, number of pounds of freight can be loaded before reaching the weight limit is :
N = 15000 - 5200 pounds
N = 9800 pounds

lol..wasn't that hard
For this case what you can do is factorize the <span>polynomial equation</span>, which would be left like follows
x ^ 3 + x ^ 2 + 9x + 9 = 0
(x + 1) (x ^ 2 + 9) = 0
Resolving, we have that the missing root is
x = -1
Answer
x=-1
