You have to divide decimal number by 2 and then to write the reminder. Then you have to continue to divide the result by 2 and so on. At the end you have to read all those reminders ( numbers 0 and 1 ) backwards and you will get the binary number. Example: Convert 10 ( decimal ) to binary.
10 : 2 = 5 | 0
5 : 2 = 2 | 1
2 : 2 = 1 | 0
1 : 2 = 0 | 1

Finally: 10 ( decimal ) = 1010 ( binary )
Answer:
12 feet
Step-by-step explanation:
30 divided by 5= 6
6 times 3= how far youve already swam(18 feet)
6 times 2= how far you have left(12 feet)
It's not the difference of squares, rather it is the square of a difference. That leaves a perfect square trinomial, which narrows your selection to two choices. An expression with 2 terms is not a trinomial, so that further narrows your selection. The appropriate choice is
... (4xy -3z)² = 16x²y² -24xyz +9z², a perfect square trinomial
_____
The expression you have in your problem statement has no z term, so none of the choices is applicable to that one.
