the electron in benzene are delocalised making d ring to be elctron rich,thereby undergoing electrophilic substitution.benzene cannot undergo nucleophillic substitution,it can only undergo if it is substituted with an electron withdrawing group
You could graph this Polynomial by using substution to solve for two points..which will define a line. If x=16, then y=0, If x=0, then y=8. Graph this line and you have the solution set for the equation.
The standard substution for buttermilk is to add one teaspoon lemon juice or vinegar to one cup of regular milk, which will give pretty much the same result as commercial buttermilk.
The perimeter of a rectangle is 2L + 2W. L will be used for lenght. Since the width is 6 inches less than the lenght, width can be defined as L-6. So you use substution. 2(L) + 2(L-6) = 52 2L + 2L -12 = 52 4L = 64 L = 16 Since L = 16 and the width is L-6 --->16-6 = 10 for your width.
