mark this and return

Step-by-step explanation:

we know that

A trinomial in the form  is said to be perfect square, if only it satisfies the condition

Squaring a binomial creates a perfect square trinomial

so

Verify each case

case 1) x^2-9

in this problem we have

----> is not true

so

Is not a perfect square trinomial

----> is a difference of squares

case 2) x^2-100

in this problem we have

----> is not true

so

Is not a perfect square trinomial

----> is a difference of squares

case 3) x^2-4x+4

in this problem we have  

----> is true

so

Is a perfect square trinomial

case 4) x^2+10x+25

in this problem we have  

----> is true

so

Is a perfect square trinomial

case 5) x^2+15x+36

in this problem we have  

----> is not true

so

Is not a perfect square trinomial

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column

answer is 33
