9x^2+6x factorise fully

What is the best approximation for the area of a circle with a radius of 4 m ? use 3.14 to approximate pi

Identify the initial amount a and the growth factor b in the exponential function. a(x)=680*4.3^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.
