A person was modeling a growing population with a growth factor of 1.5 using pennies. They started with 4 pennies and flipped all 4 pennies. For every penny that landed heads up another penny was added to the pile. Then, the new pile of pennies are all flipped and again for each one landing on heads another penny was added. The process is repeated several more times. Which of the below would the most reasonable number of pennies to be expected to be in the pile after pennies were added just after the 5th flip?​

answer: it's upside down and i can't read it

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

see below

step-by-step explanation:

x+2> 6

subtract 2 from each side

x+2-2 > 6-2

x > 4

there is an open circle at 4 since is it is greater than and the line goes to the right
