Bargain's Warehouse has a 3 shirt special. Christina bought 3 shirts on sale for $35.97. If she would have only bought one shirt, she would have paid $16.24. How much money is Christina saving on each shirt by buying the 3 shirts on special?

The answer would be 12.75.

Christina saved $12.75 on her 3 shirts

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
