1. If Quad. DECK is a parallelogram. Complete. KT = 2x + y, DT = x + 2y, TE = 12, and TC = 9,
then x = ? and y = ?

2. DE = x + y,
EC = 12, CK = 2x - y,
KD = 3x - 2y, thens x =?, y=? and the perimeter of DECK =?

3. If m<1 = 3x, m<2 =4x, and m<3 = x squared -70, then m
4. If m<1=42, m<2= x squared, and m
Thanks! If you could at least tell me the kind of work I need to do.
