How can you use properties of operations to expand expressions I need this ASAP please answer

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

Complete the solution of the equation. find the value of y when x equals to 1 9x-5y=29

Consider this equation. |y + 6| = 2 what can be concluded of the equation? check all that apply. there will be one solution. there will be two solutions. the solution to –(y + 6) = 2 will be also be a solution to the given absolute value equation. the solution(s) will be the number(s) on the number line 2 units away from –6. the value of y must be positive since the variable is inside absolute value signs.
