Acd that is originally priced at $15.85 red-tagged for the sale. what is the sale price of the cd

How many solutions does the nonlinear system of equations graphed below have? a. one b. zero c. four d. two

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.
