Find the coefficient of variation from the following data mean=4 variance=25​

Before simplifying, how many terms are there in the expression 2x - 5y + 3 + x?

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.

Which graph has figures that can undergo a similarity transformation to justify that they are similar? (obviously not the third one)
