Solve x4 – 17x2 + 16 = 0. Let u =

What value of x is in the solution set of 4x – 12 s 16 + 8x?

How many solutions does the nonlinear system of equations graphed below have?

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.
