Let it takes Todd X hours; Tom Y hours. X=Y+3 For one hour, Todd paints 1/X part of the bedroom, Tom - 1/Y; together - 1/X+1/Y 1/(1/X+1/Y)=2 2(X+Y)=XY 2(2Y+3)=(Y+3)Y 4Y+6=Y^2+3Y Y^2-Y-6=0 => Y=3, X=6

B3=20 The sum=B1/(1-q)=3*B1 =>q=2/3 B3=B1*q^2 20=B1*4/9 =>B1=45
trig
3sin^2(x)+sin(x)cos(x)=2sin^2(x)+2cos^2(x) sin^2(x)+sin(x)cos(x)-2cos^2(x)=0 Divide by cos^2(x) tan^2(x)+tan(x)-2=0 (tan(x)+2)(tan(x)-1)=0 tan(x)=-2 => x=-Arctan(2)+pi*n tan(x)=1 => x=pi/4+pi*n
