One polynomial identity that crops up often in various areas is the difference of squares identity:
A2-b2=(a-b) (a+b)
We meet this in the context of rationalising denominators.
Somebody can estimate the length of a book by using a ruler and rounding it to the nearest whole number.

Y=12/x
12/2=6
12/4=3
12/8=1.5 or 3/2
12/12=1
Answer is b
<h3><u>
Answer:</u></h3>
<u>Option A (Yes because 3 x 2 = 6 and 14 x 2 = 28.) is correct.</u>
<h3><u>
Step-by-step explanation:</u></h3>
<u>This is because if we simplify 3/6 and 14/28, both of them will get 1/2. This means that only A and C are possible.</u>
- => Option A is correct because 3 x 2 does equal 6 and 14 x 2 does equal 28.
- => Option C is incorrect because 3 x 5 does not equal 14 and 6 x 5 does not equal 28.
