The GCF is 2x.
(2x - 9)(2x - 9) or (2x - 9)2
If that's - 8x - 5, the answer is (2x + 1)(2x - 5). If that's + 8x + 5, it gets ugly in a hurry.
That would be 2X the chases, and 2X the searching.
x2+2x-63 = (x-7)(x+9) when factored
28 + 2x = 120 2x = 120 - 28 2x = 92 x = 92/2 x = 46
2x2-1x-120 = (2x+15)(x-8) when factored
4x2-4x-120 = (2x+10)(2x-12) when factored
4x2-4x-120 = (2x+10)(2x-12) when factored
x2+2x-120 = (x+12)(x-10) when factored
2x/3=x/2+20 (2x/3=x/2+20)6 4x=3x+120 4x-3x=120 x=120
1/5 of 120 = 24 =length and let the width be x: Perimeter = 2(24+x) = 120 48+2x = 120 2x = 120-48 2x = 72 x = 36 Therefore: length = 24 cm and width = 36 cm Check: 24+24+36+36 = 120 cm
If: 2x+2x+x+x = 360 degrees then x = 60 degrees. Therefore angles are: 60 degrees, 60 degrees, 120 degrees and 120 degrees
y2 - 5y + 2x - x2 - 120 is not a circle. It is a hyperbola rotated through 90 degrees.

Let the number be x If: 2x+60 = 120 Then: x = 30
We are going to have x be the width and y the length in this one. This is a pretty basic substitution problem hiding behind some geometry. Here are the two equations that you need. Y=2x is given and 2x + 2y = 120 is because perimeter=sum of all the sides. 2x + 2y = 120 y=2x Now just plug in either y or 2x into the first equation. y + 2y = 120 Combine like terms 3y = 120 clear the three with division. y=40 Now that the y value is known, simply plug that into the second equation. 40 = 2x and clear the two x=20 Simply plug those numbers into the area equation of a rectangle (length x width) A = 20 * 40 A=800
