Answer:
Step-by-step explanation:
To prove a quadrilateral a parallelogram we prove,
1). Length of opposite sides are equal.
2). Slopes of the opposite sides are same.
Length of AB =
=
=
Length of BC =
=
Length of CD =
=
Length of AD =
=
Therefore, AB = CD and BC = AD (Opposite sides are equal in length)
Slope of AB =
=
= -1
Slope of BC =
= -3
Slope of CD =
= -1
Slope of AD =
= -3
Slope of AB = slope of CD and slope of BC = slope AD
Therefore, AB║CD and BC║AD
Hence ABCD is a parallelogram
Answer:
(x - 1) x (5x + 4)
Step-by-step explanation:
5 x 2 – 4 = 6
5 x 4 – 4 = 16
6 x 2 – 11x – 4 = 56
5 x 2 – x – 4 = (x - 1) x (5x + 4)
