You have at most 6 hours to spend at a fair and at a planetarium. You want to spend at least 2 hours at the fair and more than 2 hours at the planetarium. Let x be the number of hours at the fair and let y be the number of hours at the planetarium. Which system represents the situation?

the line of

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.

sorry

step-by-step explanation:

sorry, but im pretty sure its a now that i look at it

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
