Answer:
-5x-3y^3
Step-by-step explanation:
x-3y^3+3x^3-5x-x^3-x-2x^3
If this a ratio, then the simplified form would be 2cm : 1cm I believe (6/3 = 2 and 3/3 = 1 so 2:1)

Step-by-step explanation:
Answer:
a) 160°
b) 18 sides
Step-by-step explanation:
Interior angle = 180 - exterior
= 180 - 20 = 160°
Each angle of a regular polygon:
[(n-2)×180]/n = 160
180n - 360 = 160n
20n = 360
n = 18
Alternate approach for no. of sides:
360/n = each exterior angle
360/n = 20
n = 360/20 = 18
