Answer:
if a polygon is square,then it is also a rectangle is correct
Step-by-step explanation:
1)if a polygon has 4 right angles,then it is a square is wrong since in the statement a square has all its angles as right angles but it need not imply that it is a square as it could also be a rectangle
2) polygon need not have four right angles eg:rhombous with angles 60°,60°,120°,120° is also a polygon
3)every polygon need not be a rectangle as it could be square
4)if a polygon is square, then all its angles are right angles and if all its angles are right then it is rectangle.
hence option 4 is true.
Answer is 1290.67. I rounded to the nearest tenth but it goes on.
Answer:
20/n+10 = 10/n+20 n
multiply both side n,
n (20/n+10) = n(10/n+20 n)
20+10n = 10+20n^2
20+10n -20 = 10+20n^2 -20
10n = 20n^2 -10
10n - 10n = 20n^2 -10 -10n
0 = = 20n^2 -10 -10n
20n^2 -10 -10n = 0
n = 1 or n = -0.5
Step-by-step explanation:
2/5
2 out of 5
means 2/5
or 4/10, whichever
