Write this number in standard notation- (btw 1/10 means a fraction) (5 × 10) + (6 × 10) + (7× 1/10) + (3 × 1/10)

Find the center and the radius of the circle with the equation: x^2-2x+y^2+4y+1=0?

Formulate alisha has a number in mind. if she adds three to her number the result is less than five. use this information to write and solve an inequality about alisha's number. then graph the solution set.

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.
