Which of the expressions below can be factored using the difference of squares method?
1 answer:
Answer: A. .
Step-by-step explanation:
- A difference of squares problem is factored as :
- For this both terms in the form of squares and a minus sign between them.
From all the options only option A has both terms square and they minus sign between them.
Also,
Here a= 3x and b= 4
Hence, the correct answer is A. .

First off, let's convert the percentages to decimal format, so our 77% turns to 77/100 or 0.77, and our 55% turns to 55/100 or 0.55 and so on
now, the sum of both salines, must add up to the 77% mixture, let's say is "y"
so, 11 + 4 = y, and whatever the concentration level is, must also sum up to the mixture's concentration of 77%
anyway thus
solve for "x"
