A. Is not a difference of squares
B. Is a difference of squares: (y − 5)2
C. Is a difference of squares: (y + 5)(y − 5)
D. Is a difference of squares: (y + 5)2
Option: C is the correct answer.
C. Is a difference of squares: (y + 5)(y − 5).
We are given a polynomial expression in terms of the variable y as follows:
Now this expression could also be written as:
This means that the expression is a difference of squares.
Also, we know that:
Here,
Hence,
Answer:
6cm is the missing length
Step-by-step explanation:
See the 10cm and the 4cm?
If you look at in a way if you added 6 more centimeters to the 4cm it would be 10, leaving 6cm as the missing length.
