Answer:
it's 800 ft
Step-by-step explanation:
because again when you want to find the area of anything you mulipuly so
10 x 20= 200 then you get the 200 and times it by 4 so 200 x 4 = 800
hope this helps!
Answer:
x= - 13
Step-by-step explanation:
2(3x+6) = 3(x-9)
6x+12 = 3x -27
-3x -3x
3x+12=-27
-12 -12
3x= -39
/3 /3
x= - 13
<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:
y= -5x-5
Step-by-step explanation:
because m=y2-y1/x2-x1 and then you plug in one of the point to find the y intercept or b and the answer you should get is -5 for be so it ends up being y= -5x-5
