take 360 and divide by the number of sides
regular means the sides are equal therefore the angles are equal
360 /4 =90
360 /5 =72

Greeting!
15x² = x + 2
15x² - x -2= 0
Factor left side
(5x-2)(3x+1)=0
Set factors equal to 0
5x - 2 = 0 or 3x + 1 -0
x = 2/5 or x= -1/3
I hope that helps!
Brainlest answer :)
Answer:
y = -8x + 3
Step-by-step explanation:
plug in the point and the slope into the slope intercept formula (y=mx+b)
the slope will be the same since you want the line to be parallel
11 = -8(-1) +b now solve for b
11 = 8 + b
-8 -8
3 = b
now write the equation with only the slope and the y intercept
y = -8x + 3
Answer:
98
Step-by-step explanation:
100-65=35
Turn 35 into a percent then a decimal, later multiply it by 280
