What happens when you add seven and three, then multiply that by two?

Solve 3x-18=2y and 5x-6y=14 by elimination or substitution . show all !

Which expression is equivalent to -5(3x - 6/7)

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.
