Two isosceles triangular prisms were joined at their bases to form the composite solid shown. The width of base of both prisms is 6 units. A triangular prism. The triangular sides have a base of 6, height of 4, and side lengths of 5. The height of the prism is 10. A second triangular prism. The triangular sides have a base of 6, height of 2, and side lengths of 3.6. The height of the prism is 10. What is the surface area of this composite solid? square units 104 122 158 208

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.
