The figure is 1/4 of a circle.

quarter circle with horizontal radius and vertical radius meeting at the bottom left. the horizontal radius is labeled 3 feet.

what is the exact area of the figure?

3/4π ft.²

3/2π ft²

9/4π ft²

9π ft²

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

1260=3*6*7*10=3^2*2^2*7*5 perfect cude = 3^3*2^
