Study TABLE 1 and answer the questions that follow:
1.1.1
Determine the value of A, B and C
1.1.2
In which grade are there more boys than girls?
1.1.3
Determine the ratio of boys : girls in Grade 12 in a simplified form.​

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

vertical=18cm horizontal=18cm hypotenuse=25.5
