Two sides of a rectangle fence are 5 5/8feet long . the other two sides are 6 1/4 feet long. what is the perimeter

Supposing that 5 5/8 is both sides of the base, and 6 1/4 is both sides of the height, the perimeter is 23.

4th option is correct xy=-10

if this was to u plzz mark me the brainliest

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.
