Answer:

Step-by-step explanation:

Here there are three friends.  The number of ways of introducing them to someone is the same as the number of ways of arranging three objects in a row.

Hence this is equal to 3! ways

3!=3x2x1=6 ways

Use a special-product rule to factor the perfect-square trinomial.<br> 81y^2+ 126y + 49
Ivahew [28]

Answer:

The perfect -square trinomial

                  (9y+7)²

Step-by-step explanation:

<u><em>Explanation:-</em></u>

Given polynomial equation

                        81 y² + 126 y +49

               ⇒     9² y² + 2(9)(7)y + 7²

                ⇒   (9y)² + 2(9)(7)y +7²

we will use formula

   (a+b)² = a² + 2ab +b²

             ⇒ (9y+7)²

<u><em>Final answer:-</em></u>

The perfect -square trinomial

                  (9y+7)²
