An email spam reaches three readers. each of them forwarded the same email to three different readers. each of these new readers further forwarded the same email to three different readers, who each forwarded the same email to yet again three different readers. how many people have read that email?

12 readers

Step-by-step explanation:

The first time there were three readers. They forwarded it to three more. There was another set of three and another. 3*4 is 12.

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
