The number of sides and number of angles is proportional, for it takes two sides to make an angle. So there are more sides.
Also a cube is not a polygon because a polygon is two dimensional and a cube is 3d.

Answer:yeet
Step-by-step explanation:
Let the rate of the current be x mph and rate of the boat in still water be y mph.
So the relative speed of the boat with the current ( downstream) = y + x and against the current (upstream) it = y - x.
Then , using speed = distance / time:-
y - x = 120/3 = 40
y + x = 120/2 = 60
Adding the 2 equations:-
2y = 100
y = 50
And substituting in the frst equation:-
50 - x = 40
x = 10
Answer:- Rate of boat in still water = 50 mph and rate of the current = 10 mph.
-30-5x=-4x-6(5+4x)
First, you need to use the distributive property on the right to get -30-5x=-4x-30-24x
Then, you can add like terms to get -30-5x=-30-28x
Then, you can add 30 to both sides and add 5x to both sides to get 0=-23x
Finally, you divide both sides by -23 to get 0=x
