Allie's dad has asked Allie and her little brothers to rake the leaves in their yard. They rake all afternoon and fill a number of bags with leaves. Then, when Allie isn't looking, her brothers empty 5 of the bags to make a giant leaf pile! Allie is frustrated that only 7 bags of leaves remain. Which equation can you use to find the total number of bags b that Allie and her brothers fill with leaves? b/5 = 7 b + 5 = 7 b - 5 = 7 5b = 7 Solve this equation for b to find the total number of bags Allie and her brothers fill with leaves.

your question is incomplete, write all the numbers in the sequence that it tells you.  

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
