Quadrilateral DEFG is formed by the point D(-5,3) E(3,5) F(2,1) and G(-6,-1). 1. state 3 properties of a parallelogram.
2. use three different methods to show thst DEFG is a parallelogram.​

idk

step-by-step explanation:

i don't know

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.

3; 9 is 8 to -4
