20 multiplied by 300 is 6,000.
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
20x + 4 = 4(5x + 1)
x2 + 20x - 39 = 0: Add 61 giving: x2 + 20x + 100 = (x + 10)2
x2-20x+100 = (x-10)(x-10) when factored
5x2 + 20x = 0 5x(x + 4) = 0 x = 0 and -4
280
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
The total magnification power of a microscope is calculated by multiplying the magnification of the ocular lens by that of the objective lens. In this case, with an ocular lens of 20x and an objective lens of 15x, the total magnification would be 20x * 15x = 300x. Thus, the total magnification power is 300 times the actual size of the specimen.
It is the same as: 9+20x+20 = 20x+29
20x
If: 20x = 3.65 Then: x = 0.1825
11x = 20x +1811x-20x=18x(11-20)=18-9x=18x=-2
The GCF is 20x.
The LCM is 140x.
10 - 20x = (10) (1 - 2x)
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)
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
