I am a trapezium, identify my properties from the following: a. my opposite sides are parallel // b. I am a quadrilateral // c. I have all the sides equal

a. my opposite sides are parallel

FALSE. Only the basis sides are parallel.

b. I am a quadrilateral

TRUE. A trapezium has 4 sides.

c. I have all the sides equal

FALSE. The trapezium is a special shape in that it does not, unlike the square or rectangle, have to have any equal side lengths.

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.
