3logbase5(x^2+9)-6=0

can somebody me solve this ? if you can, don't just say the answer, i want to understand how to do this so an explanation would come in handy and you. ^^

Me write an equation for the interior angles of this triangle that uses the triangle sum theorem

Fill in the blank 1. a rhombus is a rectangle a) always b) sometimes c) never 2. a square is a quadrilateral a) always b) sometimes c) never 3. a trapezoid is a kite a) always b) sometimes c) never 4. a quadrilateral is a kite a) always b) sometimes c) never 5. a square is a rhombus a) always b) sometimes c) never 6. a parallelogram is a rectangle a) always b) sometimes c) never

Lines a and b are perpendicular. if the slope of line a is 3, what is the slope of line b?
