The midpoints of the sides of the trapezoid are:
M ( - 1 , 1 ), N ( 1, - 1 ), P ( 3, 1 ), Q ( 1, 3 ).
MN = NP = PQ = QM = √ ( 2² + 2² ) = √ 8 = 2√2
∠MNP = ∠NPQ = ∠PQM = ∠QMN = 90°
Answer:
The quadrilateral formed by joining the midpoints of the sides of the trapezoid is a square.

Answer:
x
=9
y
=2
Step-by-step explanation:
You can simply expand the factorised form out:
y = 14x² - 21x + 10x - 15
y = 14x² -11x -15
