Answer:
Step-by-step explanation:
The inradius is given by the area of the triangle divided by the semiperimeter.
The semiperimeter is .
Thus, by Heron's formula, the area is .
Therefore, the radius is
21(3n+7)=?
(63n+147)=? After multiplying
63/147=2.33333. After dividing 147/63 plz let me know if I’m wrong.
Answer: 21(3n+7)=2.33333
