Help me please, the words that got cut off were exponent by 1

What values of x satisfy the inequality x^2-9x< 0? how is your answer shown on the graph?

The figures below are made out of circles, semicircles, quarter circles, and a square. find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations).

Which shows the correct substitution of the values a,b and c from the equation 1=-2x+3x^2+1
