PLEASE HELP "Write an expression in simplest form that represents the perimeter of the polygon. "

46x - 5

Step-by-step explanation:

Perimeter is the length around a polygon, which would be all of the sides lengths added up. 8x + (8x-4) + (10x+4) + (6x-5) + 14x = 46x - 5.

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.
