Answer:
The given points isn't define a parallelogram.
Step-by-step explanation:
As we know,
⇒ The opposite sides of a parallelogram are equal.
The given points are:
(x1, y1) = M(2,4)
(x2, y2) = I(1,2)
(x3, y3) = L(5,1)
(x4, y4) = K(4,−1)
Now,
On applying the Distance formula, we get
MI =
On substituting the given values, we get
=
=
=
IL =
=
=
=
LK =
=
=
=
KM =
=
=
=
Here, MI = LK = √5
IL ≠ KM

A:
1) Use difference of squares:
2) Use difference of squares:
B:
1) Factor out common terms in the first two terms, then in the last two terms.
Factor out the common term y-1
C:
1) Collect like terms
2) Simplify.
D:
a3 – a2 – ab + a + b – 1
= a3 – a2 – ab + b + a – 1
= a2 (a – 1) – b (a – 1) + 1 (a – 1)
= (a – 1) (a2 – b + 1)
