15 divided into 6396 show the steps on how to solve i know the answer is 42 just don’t know the step to put in order

6396÷15=426.4

15 will go into 63 4 times with 3 left

bring down the 9 now you have 39 and 15 will go into it 2 times with 9 left

bring down the 6 you have 96 and 15 will go into that 6 times with 6 left

put you decimal after the 6 and bring down a 0

60 ÷ 15 =4

0 remainder

1/800 is the right 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
