You put some money in a bank account one year ago. You have not done anything with it since. The bank takes out a low balance fee of $0.25 each month. After 8 months, you had $28 in the account. Choose the equation that best shows the money in your bank account over time. CLEAR CHECK Balance=−0.25⋅Months Balance−28=−0.25(Months−8) Balance−8=−0.25(Months−28) Balance−28=−0.25(Months+8)

the answer is 24

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
