On a coordinate plane, a trapezoid is inside of a rectangle to form 3 triangles within the rectangle. the trapezoid has points (4, 4), (4, 14), (12, 20), and (20, 16). the rectangle has points (4, 4), (4, 20), (20, 20), and (20, 4). triangle 1 has points (4, 14), (4, 20), (12, 20). triangle 2 has points (12, 20), (20, 20), (20, 16). triangle 3 has points (4, 4), (20, 16), (20, 4). complete the steps to find the area of the trapezoid. area of rectangle = square units area of triangle 1 = square units area of triangle 2 = square units area of triangle 3 = square units area of trapezoid = square units

step-by-step explanation:

answer: 40.95

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.
