A polygon is regular if each of its sides has the same length. Find the perimeter of the regular polygon.

The table below shows the height of a ball  x  seconds after being kicked.  what values, rounded to the nearest whole number, complete the quadratic regression equation that models the data? f(x)  =  x2  +  x  +  0based on the regression equation and rounded to the nearest whole number, what is the estimated height after 0.25 seconds?   feet

Me complete this proof! prove that a quadrilateral is a square. me with the steps for this proof.

Will give brainliest immeadeately true or false: the origin woud be included in the solution set for the inequality: y< 2x-5
