Answer:

$(14) \: \: \: \\ \\ 3(5z - 7) - 2(9z - 11) = 4(8z - 13) - 17 \\ \\ 15z - 21 - 18z + 22 = 32z - 52 - 17 \\ \\ - 3z + 1 = 32z - 69 \\ \\ 35z = 70 \\ \\ z = 2$

Answer 2

19.

A square is a quadrilateral because we know that sum of all angles of a quadrilateral is 360° and sum of all angles of square is also 360°. Hence it is a quadrilateral.

It is a parallelogram because opposite angles and sides are equal and parallel to each other.

Opposite sides are equal and each angle is 90°
