A restaurateur of a high-end restaurant sources a regional whiskey directly from Scotland. The cost for a single 750 mL bottle is 46 £ (pounds sterling). Suppose the exchange rate on the day the whiskey was bought was 1 USD = 0.72 £. What is the restaurateur's cost in dollars to pour a patron a 2-fluid-ounce shot of this whiskey?

step-by-step explanation:

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
