Is multiple on a boat, a cabin's window is in the shape of an isosceles trapezoid, as shown below. what is the area of the window? an isosceles trapezoid with top side 10 inches long and a longer bottom side. the height is 14 inches. the base of the triangle formed from the height on the right is labeled 4 inches. a.196 square inches b. 240 square inches c.252 square inches d.392 square inches

the answer to the expression is 83

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.
