Aiko is selling books for $12 each. She wants to make more than $180 in book sales. The inequality 12 b > 180 can be used to determine the number of books, b , she must sell in order to meet her goal. Which number line best represents the solution to the inequality?

0.32

step-by-step explanation:

2.24/7

17

step-by-step explanation:

51/3=17

thus 17 is your answer.

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: (1,3) (3,-1) (5,-5) ?
