Part a: the length of a garden is 51 1/3 feet. one section of fencing is 3 2/3 feet long. part b: for each piece of fencing, 4 stakes are used to secure it in place. the stakes are equally spaced along the fencing piece, with one stake at each end. how far apart are the stakes on one piece of fencing

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.

sine
