Write two equations with the given information:
1) x = 2y ( x is twice the value of y)
2) x + y = 42
Replace x in the second equation with the value of x in the first equation:
2y + y = 42
Simplify:
3y = 42
Divide both sides by 3:
y = 42 / 3
y = 14
Now we have the value for Y, solve for x by replacing y with 14:
x = 2y
x = 2(14)
x = 28
X = 28 and y = 14
If 24 is a solutoin of x, n has to be 24 squared. 24*24=576
180(n-2)
N is number of sides
Nonagon has 9 sides.
9-2=7
7x180=1260
