A 3 inch radius circle is drawn inside a 7 inch radius circle. If you throw a dart at these circles, what us the probability you land inside the smaller circle??

sorry i just need to anwers this to get points

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

it would be a on edgenuit y

the diagram below is your final answer

10 - 75

step-by-step explanation:

there's nothing attached so it's most likely anything in that range.
