What's the perimeter of a square with a side measurement of 6 in.? a. 12 in. b. 18 in. c. 24 in. d. 36 in.

Perimeter = 4 X Sides

P = 4 S

P = 4 (6 )

P = 24

d) -1

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.
