Answer:
7
Step-by-step explanation:
In this equation, n = # of sides
Area = n * (side length)² / 4*tan (180 / n)
Area = 5 * 4² / 4 * tan (36)
Area = 80 / 4 * 0.72654

This is an easy way to solve multiplication with alot of zero's
Add only the numbers, then add the sum of the zeros
So with this problem we do this:-
5*4 is 20, plus the zero in the 50, so the answer is 200
Now we can do the other one:-
5*4 is 20, plus the 4 zeros that we removed is 200,000
Hope I helped. :)
Answer:
a. 9
Step-by-step explanation:
Observe that 2x is the x-term with the smallest coefficient, and that x-terms are found on both sides of the equal sign. Further, observe that constants are also found on both sides of the equal sign, and the constant on the side opposite 2x is 3.
To solve this, you don't want either of those terms, 2x or 3, where they are. Subtract that sum from both sides of the equation:
3x +3 -(2x +3) = 2x +12 -(2x +3)
x = 9 . . . . . . collect terms
