Eh whats the answer. thanks

Iwant to know what 3g+5h+4g-2h is my teacher is too selfish to tell us

Which of the following expressions is equal to 2x^2+8

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.
