2/3(6k-30)+k=100 this is the one I need help

Me complete this proof! prove that a quadrilateral is a square. me with the steps for this proof.

Which is the graph of this function 3 square root of x plus one if

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.
