Answer:
Step-by-step explanation:
<u>Given</u>
<u>Substitute and solve for n:</u>
- 42 = n² + n
- n² + 2*1/2n + 1/4 = 42.25
- (n + 0.5)² = 42.25
- n + 0.5 = √42.25
- n + 0.5 = 6.5
- n = 6
Correct option is C
Answer:
6
Step-by-step explanation:
We can use the geometric mean theorem:
The altitude on the hypotenuse is the geometric mean of the two segments it creates.
In your triangle, the altitude is the radius CM and the segments are AC and BC.

Answer:
174.68
Step-by-step explanation:
Use PEMDAS. First, multiply 1/-25 by 8. (-8/25 or-.32)
Then, add 175 and y should= 174.68.
Answer:
49
Step-by-step explanation:
The area of a triangle is
A = 1/2 bh
A = 1/2 (14)*7
A =49
