When dustin goes to work, he drives at an average speed of 55
miles per hour. it takes about 2 hour and 15 minutes for dustin to
arrive at work. his car travels about 25 miles per gallon of gas. if
gas costs $2.75 per gallon, how much money does justin spend to
travel each mile to work?

incomplete question. how do you expect anyone to you when you do not post the question in its entirety?

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

b.
