Mr williams is planning a seventh grade field trip to a math museum. school policy requires a minimum of 2 adults as chaperones for every 9 students on the trip, and allows a food budget of $6 per person. educational group pricing at the museum is $4.50 per student and $7.25 per adult. there is also a bus parking fee that is 4% of the total ticket price. there are 171 students in seventh grade. how much money does mr. williams need to budget for the museum tickets and parking?

good luck on your studies! : )

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
