Ken wants to build a table and put a border around it. the table and border must have an area of 3,276 square feet. the table is 36 inches wide and 72 inches long without the border. which quadratic equation can be used to determine the thickness of the border, x?

,

Step-by-step explanation:

The area of the table and border can be computed by using the following second order-polynomial:

The thickness of the border can be determined by expanding and simplyfiying the algebraic expression:

The roots of the polynomial are:

and

Knowing that length is a positive unit, the first root is the only solution that is reasonable:

what are you doing do you need examples of variable questions?

step-by-step explanation:

5a-1=9               bring the one over the =

5a=10                     divide by your variable

a=2

3a-24=0

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15
