Find the simplified product. 5/n+1 times n+1/n+3

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

Rewrite so the subject can be y in the formula d=m-y/y+n

Answer asap! show all work! find the number of complex roots, the possible number of real roots and the possible rational roots of the polynomial function. then, solve for all roots. x^3 + 2x^2 + 3x + 6 = 0
