If A=ab and B=ba then A-B=ab-ba which means 10a+b-10b-a=9a-9b=9(a-b)
so A-B is divisible by 9

Answer:
=14x3−166x2−208x
Step-by-step explanation:
(7x+8)(x)(2x−26)
=((7x+8)(x))(2x+−26)
=((7x+8)(x))(2x)+((7x+8)(x))(−26)
=14x3+16x2−182x2−208x
=14x3−166x2−208x
Answer:
The measure of each angle is 18°
Step-by-step explanation:
we know that
A <u><em>regular polygon</em></u> is a polygon whose all sides are equal and also all angles are equal.
so
In this problem

Solve for x



Substitute the value of x

therefore
The measure of each angle is 18°
