2 x 2 = 4 x 60 = 240
2 x 4 x 4 2 x 2 x 8
PQR P=2 Q=4 R=5 2 x 4 x 5 = 40
x^2/x +2=4/x +2 (x^2/x)-(4/x)=0 (x^2-4)/x=0 x^2-4=0 (x+2)(x-2)=0 x=±2
y varies directly as x y=kx, where k is any constant y = 4 when x=-2 4 = k (-2) 4 =-2k k=-2 Therefore, y=-2x When x=30 y = -2(30) = -60

-2
2 x 2 = 4 x 60 = 240
x = -2

-(2)Squared = 4
-x -2 = 2 so -x = 2+2 = 4 and so x = -4
4 + x = 2x --> 4 = 2x - x --> 4 = x: x = 4
No, it is not.
-1/2
4+ X equals 2X. Subtract X from both sides. Four equals X
