Marlo is sitting on a dock playing with a ring on her finger at a elevation of 2 1/4 meters above the surface of the water .the ring falls off her finger and lands at an elevation of -2 1/2 meters. which values best represents the distances the rings falls?

fast you smart people

5/20 so 25%

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

i would say true? if the unit was informational and it "refreshed your understanding", then true.
