Drop the vertical on the right (see image below)
find '30' via pythagorean theorem
then find '12' from 94 - 30 - 52 = 12
then find 20 from pythagorean theorem (again)
Now you have the length of all four sides 52 + 34 + 94 + 20 = __________ units
The only terms in the poynomials that will provide the constant in the product polynomial are the costant terms (which the question states are the same )
so constant * constant = 81 the constant is 9
6 C 2 = 15 ways to paint two faces
only ONE way to paint faces resulting in a product of 4 (...paint the 1 and the 4)
15 -1 = 14 ways to paint two faces that do not result in painted faces = 4
x=2a+1
= (2)(-1)+1
x = -1
y = [2(-1) - 3(-1)^2 ] / 3
= (-2 -3)/3
= -5/3
-(4-5+2)-3-[1-[6+(-3-1)-(-2+4)]+3-4 though a ' ] ' is missing
- (1) - 3 - [1-[6 + ( -4) - (2) ] -1
-4 - [1- [6 -6] -1
-4 - 0
-4 possibly depends on the missing ]
x = beginning value
.9x after monday (10 % loss leaves 90 % value)
.9x * .8 after tuesday
.9x * .8 * .7 after wed = .504x is the value on Wed a loss of 49.6 %
Diagram is missing......
See original post....... ~EP
Multiply both sides of the equation by r+4 to get
r^2 -3r-17 = 2r^2 +15r + 28 simplify
r^2 +18r + 45 = 0
(r+15)(r+3) = 0 You should be able to finish......
SUm of the interior angles of the 10 sided polygon (n-2)* 180 = 1440 degrees
1440/10 = 144 degrees each angle the external angle is 180 - 144 = 36
alpha goes from 4 to 8 or 4 external angles 4 * 36 = 144 degrees
Here area couple of pictures:
