6c^2 - c + 1 + 4c - 2c^2 - 8c
= 4c^2 - 5c + 1
= (4c - 1)(c - 1)

Maurinko [17]

Answer:

A quadrilateral formed by the vertices A(11,-7), B(9,-4), C(11,-1), and D(13,4) forms a rhombus

If the vertex C(11,-1) were shifted to the point C'(11,1), quadrilateral ABC'D would be a kite

Step-by-step explanation:

A quadrilateral formed by the vertices A(11,-7), B(9,-4), C(11,-1), and D(13,4) forms a rhombus. A rhombus is a quadrilateral whose all sides have equal length means it has four equal sides.

If the vertex C(11,-1) were shifted to the point C'(11,1), quadrilateral ABC'D would be a kite because a kite has two pairs of equal sides. A kite is a quadrilateral whose four sides can be grouped into two pairs of equal-length sides which are adjacent to each other....

Add: 3x(x-y+z) and 2y (x+y-z)

hodyreva [135]

Answer:

3x^2 + 3xz + 2y^2 - 2yz - xy

Step-by-step explanation:

(1) multiply it to get

3x^2 - 3xy + 3xz and 2yx + 2y^2 - 2yz

add similar variables (-3xy + 2yx)

( the order of the variables doesn't matter xy or yx is the same)

we get -xy

and then after that simplifying we get 3x^2 + 3xz + 2y^2 - 2yz - xy
