Within stellar systems, the average separation between planets is roughly 10 to the 16 cm and the average planetary radius is typically 10 to the 16 cm. the void ratio for this stellar system is roughly 10 to what power? [hint: remember that volume is proportional to the cube of the linear size]

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

it would be a on edgenuit y
