5. The table below shows the data of a person's height (in centimeters) and the length of their foot (in centimeters). Calculate the line of best fit for the data.
Height (cm)Foot Length (cm)
10215.5
10916
13019.3
12618.8
11816.5
10315.6
12016.8
11416.2
12218
12418.5

the discriminant is 64 + 4*1*12 = 112

this is prime.

step-by-step explanation:

unless if u could do my questions, if not i wouldn't want to

idk

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
