28 units

Step-by-step explanation:

P= 4a

The perimeter of a square is divisible by 4 if side length is a whole number

From the given list only 28 is divisible by 4 so just guessing this is the one

can i get the link to the assignment?

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.
