Your work or words should justify your answer (explain how you know). As a math teacher, Josie frequently makes photocopies of fun activities for her students to do When the copies come out of the copy machine, they form a stack. This table shows the relationship between the number of copies in the stack, x, and the height (in millimeters) of the stack, y. According to the values in the table, do x and y have a proportional relationship? yes no

sine

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
