On a coordinate plane, parallelogram A B C D is shown. An altitude is drawn from point B to point E on side D C to form a right angle. The length of B E is 14.5. Point A is at (negative 10, 10), point B is at (4, 8), point C is at (10, negative 8), and point D is at (negative 4, negative 6). Segment BE is the altitude of parallelogram ABCD. BE is approximately 14.5 units long. What is the area of the parallelogram rounded to the nearest unit? square units

(x3 + 6x2 + 2x - 6) • (x - 1)

step-by-step explanation:

polynomial long division :

3.2     polynomial long division

dividing :   x4+5x3-4x2-8x+6

                              ("dividend")

by         :     x-1     ("divisor")

dividend     x4   +   5x3   -   4x2   -   8x   +   6

- divisor   * x3     x4   -   x3            

remainder         6x3   -   4x2   -   8x   +   6

- divisor   * 6x2         6x3   -   6x2        

remainder             2x2   -   8x   +   6

- divisor   * 2x1             2x2   -   2x    

remainder               -   6x   +   6

- divisor   * -6x0               -   6x   +   6

remainder                     0

quotient :   x3+6x2+2x-6   remainder:   0

- (2, -7)

- lines r and s and lines t and u must be parallel
