x2 −100
x2 − 4x + 4
x2 + 10x + 25
x2 + 15x + 36
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

tickets for the harlem globetrotters

show at michigan state university in

2010 cost $16, $23, or, for vip seats, $40.

total revenue = 16x + 23y + 40z

if 9 times as many $16 tickets were sold

as vip tickets,

x = 9z => x – 9z = 0, if 9 times as many $16 tickets were sold

as vip tickets,

x = 9z => x – 9z = 0, sales of all three kinds of tickets would

total $46,575.

16x + 23y + 40z = 46575, how many of each kind of ticket would

have been sold?

solve for x, y and z

x − 9z = 0

x − y − z = 55

16x + 23y + 40z = 46575

x = 1170

y = 985

z = 130
