Several local bands come together to perform an all day free concert in the park. there are 300 people in the crowd at the beginning of the concert. the number of people in the crowd gross 15% every hour. how many people are in the crown after five hours? round your numbers to the nearest whole number. answers: a: 603 b: 383 c: 133 d: 746

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

answer: the answer is 110

it would have to be 3/0
