Answer:
[211.43,216.57]
Step-by-step explanation:
1.2% of 214 is ...
0.012 × 214 = 2.568 ≈ 2.57 . . . . rounded to hundredths
Then the minimum possible value is ...
214 -2.57 = 211.43
and the maximum possible value is ...
214 +2.57 = 216.57
The range is 211.43 to 216.57.

Answer:
-4.2
Step-by-step explanation:
In centre is the centre of a circle that is inscribed in a triangle, called the incircle, i.e. circle is tangent to all three sides AND located inside the triangle. An incircle is roughly sketched in the accompanying diagram.
Since all radii of an incircle are equal, we have
4x-1=6x-5
Solving for x,
6x-4x=5-1
x=2
consequently, distance from incentre to each side of the triangle is
4(2)-1=7
check 6x-5=6(2)-5=7... checks.
Answers:
The value of x = 2
The distance from incentre to side of triangle is 7
