Presumably 300 is the perimeter if so then let length be x and the width be 20x: 2(length+width) = perimeter 2(x+20x) = 300 2x+40x = 300 42x = 300 x = about 7.142857143 units 20x = about 142.857429 units

20x-5 = 15

If the equation is -20x-5y=40 then the answer is -5y=20x+40 which equals y=-4x-8 If the equation is -20x+5y=40 then the answer is 5y=20x+40 which equals y=4x+8

It is the same as: 9+20x+20 = 20x+29

50x squared equals 20x-2 equals zero is not possible, for 20x-2 = 0 --> x = 1/10 While 50x2 = 0 means that x should be zero. So either 50x2 =/ 20x-2 or 20x-2 =/ 0

If: 20x = 3.65 Then: x = 0.1825

The best HD camera for under $200 or $300 is the Canon PowerShot SX280 HS (as of 2013). The Canon PowerShot SX280 HS has a power zoom of 20x, a large LCD, and plenty of resolution for sharp photos.

The LCM is 140x.

The GCF is 20x.

10 - 20x = (10) (1 - 2x)

20x + 4 = 4(5x + 1)

If: y = x2+20x+100 and x2-20x+100 Then: x2+20x+100 = x2-20x+100 So: 40x = 0 => x = 0 When x = 0 then y = 100 Therefore point of intersection: (0, 100)

x2 + 20x - 39 = 0: Add 61 giving: x2 + 20x + 100 = (x + 10)2

11x = 20x +1811x-20x=18x(11-20)=18-9x=18x=-2

The graphs of the two equations will intersect when x² + 20x + 100 = y = x² - 20x + 100 Subtracting x² +100 from both sides you get 20x = -20x that will only be true when x = 0. At x = 0, y = 100 for both equations - so the point of contact would be (0,100)

20 divided by .55 is 36.36364. So 20x / 0.55 is 36.36364x

12x2-20x-8 = (12x+4)(x-2)

x2-20x+100 = (x-10)(x-10) when factored

If: 20x+5y = 15 Then: y = -4x+3
