What is the quotient оf (x^3+ 3х^2 + 5х + 3)/(х + 1)?

For f(x)=2x+1 and g(x)= x^2 -7, find (f•g)(x)

If angle 2=3x +1 and angle 3=2x +4what is angle 2

White shapes and black shapes are used in a game. some of the shapes are circles. while the rest are squares. the ratio of the number of white shapes to the number of black shapes is 5: 11. the ratio of the number of white cicrles to the number of white squares is 3: 7. the ratio of the number of black circles to the number of black squres is 3: 8. work out what fraction of all the shapes are circles.
