Justin wants to use 376ft of fencing to fence off the greatest possible rectangular area for a garden. what dimensions should he use? what will be the area of the garden?
a. 89 x 99; 8811 ft
b. 92 x 96; 8832 ft
c. 94 x 94; 8836 ft
d. 93 x 95; 8835 ft

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.

8+10

step-by-step explanation:

you multiply 4 by 2 and 5 by 2
