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:

so then what are you asking?

step-by-step explanation:

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
