Arectangle sand box has a length of 5 and 1/3 feet and a width of 3 and 3/4 feet. what is the perimeter?

Perimeter of rectangle = ⇒ feet

Step-by-step explanation:

Given:

Length of a rectangular sand box =

Width of the box =

Perimeter of a rectangle =

where represents length of rectangle and represents width of the rectangle.

Substituting values given for length and width.

Perimeter of sand box =

Simplifying by adding fractions:

⇒   (Adding whole numbers and fractions separately)

⇒   feet

Whole number 8 can be written as

⇒   feet

To add fractions we take LCD for the denominators 3,4,1.

LCD for 3 and 4 = 12 as its the least common multiple of 3,4,1.

Making denominators =12 by multiplying numerator an denominator with the corresponding numbers

⇒   feet

⇒   feet

Then we simply add numerators.

⇒   feet

⇒   feet

⇒   feet

⇒   feet

Writing fraction as a mixed number by dividing 218 by 12 and writing quotient as whole number and remainder as numerator with divisor as denominator.

⇒ feet

Simplifying fractions to simplest form.

⇒ feet

Perimeter =⇒ feet  (Answer)

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.
