Answer:
I believe it is -3, althought -9 would work it needs to be simplified as low as possible and 3x3=9, therefore you can simplify 9 to 3.
Step-by-step explanation:
<h3>
Answer: 20 sides</h3>
==================================================
Work Shown:
x = exterior angle
9x = interior angle
interior + exterior = 180
9x+x = 180
10x = 180
x = 180/10
x = 18
n = number of sides
n = 360/x
n = 360/18
n = 20
There are <u>20</u> sides to the regular polygon.
Side notes:
- The formula to determine n only works for regular polygons.
- A polygon with 20 sides is known as an icosagon.
- Any pair of adjacent interior and exterior angles are supplementary. They add to 180 degrees.
Answer:
4x-6
Step-by-step explanation:
Six less than four times a number is four times x because times is multiplying and then subtracting six because less means minus (subtraction)
For points (x1,y1) and (x2,y2)
slope=(y1-y2)/(x1-x2)
(-4,-13)
(19,11)
x1=-4
y1=-13
x2=19
y2=11
slope=(-13-11)/(-4-19)=-24/-23=24/23
B is answer
To common number is 2 to divide all of them to 2
9x - 3x + x
6x + x
the simplified answer is 7x
