Complete the coordinate proof for the quadrilateral determined by the points A(-3,-1), B(-1,-6), C(-6, -8), D(-8, -3).
Prove that ABCD is a parallelogram.
=
6+1
Slope of AB =
-1+3
-8+6
Slope of BC =
-6+1
-3+8
Slope of CD =
-8+6
-1 +3
Slope of AD =
-3+8
The slopes of opposite sides (select)v equal. This means that opposite sides are (select)
ABCD (select) y a parallelogram.

Step-by-step explanation:

man its nopq i just guessed and got it right so uhh

step-by-step explanation:

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
