Circle a has center of (5, −2) and a radius of 7, and circle b has a center of (7, −8) and a radius of 35. what steps will show that circle a is similar to circle b?

rotate circle a 90° counterclockwise about the center.
translate circle a using the rule (x − 2, y + 6).
reflect circle a over the y-axis.
dilate circle a by a scale factor of 5.

answer: x=3 and y=4

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

x= 3^y
