Use the replacement set to find the solution set to the inequality c+5<16 {10,11,12}

Solve for x and y: 217x + 131y = 913; 131x + 217y = 827

Find the solution(s) to the system of equations. select all that apply y=x^2-1 y=2x-2

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.
