One car rental company charges $30 per day plus $0.25 per mile driven. a second company changes $40 per day plus $0.10 per mile driven. how many miles must you drive for a one day rental at the second company to be less expensive than the same rental at the first company? write and inequality and solve.

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.
