segment B prime C prime has endpoints located at B'(2, 0) and C'(2, 6). segment BC was dilated at a scale factor of 2 from the origin. Which statement describes the pre-image?

segment BC is located at B (1, 0) and C (1, 3) and is one-half the size of segment B prime C prime.
segment BC is located at B (2, 0) and C (2, 6) and is the same size as segment B prime C prime.
segment BC is located at B (4, 0) and C (4, 12) and is twice the size of segment B prime C prime.
segment BC is located at B (6, 0) and C (6, 18) and is three times the size of segment B prime C prime.

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

d

because parallelagram have all 4 angels the same size dependeing and a rectangle and square are oth parallelogram
