Which statement best describes the area of triangle abc shown below? a triangle abc is shown on a grid. the vertex a is on ordered pair 4 and 5, vertex b is on ordered pair 5 and 2, and the vertex c is on ordered pair 3 and 2. (5 points) it is one-half the area of a square of side length 3 units. it is twice the area of a rectangle with sides 2 units × 3 units. it is twice the area of a square of side length 3 units. it is one-half the area of a rectangle with sides 2 units × 3 units.

is the answer

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.
