Convert the equation into standard form.
25x^2-9y^2+200x+18y+166=0

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

Average acceleration: i have no idea how to do this.

Given: ae ≅ ce ; de ≅ be prove: abcd is a parallelogram. we have that ab || dc. by a similar argument used to prove that △aeb ≅ △ced, we can show that △ ≅ △ceb by. so, ∠cad ≅ ∠ by cpctc. therefore, ad || bc by the converse of the theorem. since both pair of opposite sides are parallel, quadrilateral abcd is a parallelogram.
