The basketball court in the park is a rectangle. two of the sides are 84 feet long, and the other two sides are 50 feet long. what is the perimeter of the basketball court? a. 100 feet b. 134 feet c. 268 feet d. 168 feet

the answer is c                             

268 feet

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.

answer:

c) the x-coordinate of the center of the circle increases by 3
