Elsa is taking physical fitness tests in her strength training class. Each day, her results are compared to her results from previous days. The first day she completes a test is considered the baseline, and is represented by 0
. For instance, on the first day she did the flexibility test, her result was calculated as
0
. On the second day, in comparison to her first day's result, she was able to reach
1
1
16
inches less than the first day, which was recorded as
−
1
1
16
. Then, on the third day, Elsa recorded a result of
−
5
8
.

A. On which day did Elsa reach farther: the second or third day?

B. By how much?

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

range =5

step-by-step explanation:

to find the range, we take the largest value and subtract the smallest value.

the largest value is 5

the smallest value is 0

the range is 5-0   =5
