Find the area of a rectangle with a length of 7 centimeters and a width of 24 centimeters.

168 cm^2

Step-by-step explanation:

Given,

Length ( l ) = 7 cm

Width / breadth ( b ) = 24 cm

To find : -

Area of rectangle = ?

Formula : -

Area of rectangle = l x b

Area of rectangle

= 7 x 24

= 168 cm^2

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.
