A vertical line separates the solid figure into two rectangular prisms. Which expression shows the volume of the solid figure? A rectangular prism beside another longer rectangular prism. The left prism measures 16 inches by 5 inches by 4 inches. The right prism measures 4 inches by 4 inches by 8 inches. (4 × 5 × 8) + (4 × 4 × 16) (4 × 5 × 16) + (4 × 4 × 8) (4 × 5 × 20) + (4 × 4 × 8) (4 × 5 × 8) + (4 × 4 × 20)

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.
