(english to algebra) twenty increased by the quotient of x divided by two

Express in the simplest form: (x^2+9x+14/x^2-49) / (3x+6/x^2+x-56)

Which statements about the system are true? check all that apply. y =1/3 x – 4 3y – x = –7 the system has one solution. the system consists of parallel lines. both lines have the same slope. both lines have the same y–intercept. the equations represent the same line. the lines intersect.

Write an expression that is equivalent to ( 3+14)+27.
