The diagram shows a round fountain surrounded by a circular path. The radius of the fountain is 47 yards, and the distance from the center of the fountain to the outer edge of the path is 56 yards.
The estimated area of the fountain is
v. square yards, and the estimated area of the path is square yards.
Hint: The formula for the area of a circle is A = pi r squared 2

answer:   14

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

ome people is not even worth it to even try it in the air.
