Many airlines have a size limitation for carry-on luggage. the limitation states
that the sum of the length, width and height of the suitcase must not exceed 45 inches.
a. write an inequality that describes the airlines' carry-on size limitation
b. a passenger needs to bring a soil sample on the plane that is at least 1 cubic foot. the passenger is
bringing it in a suitcase that is in the shape of a cube with side length 7 inches. write an inequality
that gives the minimum length for .

17   x 256=4352

sorry if this is wrong, i'm new.

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.
