x+3/2x-1=-2
x+3= -2 (2x-1)
x+3= -2.2x-2. (-1)
x+3= -4x+2
x+4x=2-3
5x= -1
x= -1/5
Answer:
Um for what test?
Step-by-step explanation:
Step-by-step explanation:
Each interior angle=140°
(n-2)180°/n=140°
180°n-360°/n=140°
180°n-360°=140°n
180°-140°=360°
40°n=360°
n=360°/40°
n=9
Hence, the number of sides of the polygon is 9.
It is nonagon .
