00:00 What quotient does the model Nestor made represent?
0 3.21 + 3 = 1.07
0 1.47 + 7 = 0.27
0.21 + 7 = 0.03
0.81 - 3 = 0.27

0.81-3=0.27

Step-by-step explanation:

0.81-3=0.27 it

It is similar to 3.21÷3=1.07 this is division

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
