What is the value of n so that the expression x2 11x n is a perfect square trinomial

Step-by-step explanation:

Since we know that perfect square trinomial formula states that any trinomial of the form is said to a perfect square if it satisfies the condition .

We are given an expression and asked to find value of n for expression to be a perfect square trinomial .

Let us compare our expression with perfect square trinomial formula.

We can see that a=1, b=11 and c=n.  

Let us find value of n by substituting our given values in .

.

Therefore, will make the expression a perfect square trinomial.

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you
