Look at the line graph below. It shows last year’s crowd numbers at the arena. (Graph Attached)

How many people from the under 30 group attended in July?
How many people from the 30 and above group attended in May?
In which months did people from the 30 and above group make up the majority of the crowds?
How many more people from the under 30 group attended in February than the 30 and above group?

answer: 0.64

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
