Explanation:

The first row indicates the first term is 10. The small "1" is the index number. That means is next followed by and so on.

To generate the next term, we follow this recursive step:

It means "whatever the nth term is, we add 4 to it to get the next term "

In other words, we add 4 to each term to get the next term.

Eg: 10+4 = 14 and 14+4 = 18

The recursive step could be rewritten as based on how you frame things.

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
