Factor the following expression.
10,5 + 513 – 14,2 - 7

Iwill give ! if m∠a=59 and m∠3=81°, what is m∠b? m∠b= _[blank]_°

Write the expression in complete factored form. 5n_(c - 3) - n(c - 3) =

The diagonals of a quadrilaretral intersect at (-1,4). one of the sides of the quadrilateral is bounded by (2,7) and (-3,5) determine the coordinates of the other side in order for the quadrilaretral to be a square.
