In which of the following expressions is the coefficient of term "x" 1? 2x^2+x−9
2 x squared plus x minus 9

x^2+2x+7
x squared plus 2 x plus 7

3x^2−x−5
3 x squared minus x minus 5

2x^2−3x+1

The sum of these consecutive integers is equal to 9 less than 4 times the least of the integer. find the three integers

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.
