Caitlyn started collecting shells in 2005. She records how many shells are in her collection each year. Years since 2005# shells

030

139

248

357

What is the initial value?

0

9

30

57

30.

Step-by-step explanation:

The initial value is the value that she starts out with.  This means that she is referring to year 0.  According to the chart, on year 0, she collected 30 shells.

The answer is 30.

answer: i think one of the answer is $150 and $300?

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
