A polygon is regular if each of its sides has the same length. Find the perimeter of the regular polygon. One side is 5-2x
The other one is -4x + 9
One side is blank
It's a triangle

6

Step-by-step explanation:

So if it is a triangle it is a equilateral triangle.

if all the sides equal eachother, we know to find x.

5-2x=-4x+9

+4x

5+2x=9

-5    -5

2x=4

/2

x=2

So if a triangle has three sides, we multiply 2 x 3 or (x) times the number of sides.

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
