Answer : x=3
Step-by-step explanation:
Explanation:
2x+3=9
We want to find the variable x, so we have to make it alone. To do so, first subtract 3 from both sides of the equation:
2x+3 − 3=9 − 3
2x=6
Now divide both sides by 2:
2x2=62
So the final answer is:
x=3

Given:
A regular polygon with three vertices and side 14 cm.
To find:
Area of the regular polygon.
Solution:
