Answer:
16x^2 - (12+12)x + 9
16x^2 -12x -12x +9
4x(4x-3)-3(4x-3)
(4x-3)(4x-3)
hence length of one side is 4x-3
The answer is 12. How did I get it?

Answer:
The expected number of defective chips per year will be 3960 numbers.
Step-by-step explanation:
In a semiconductor company, a quality control test machine found that 22 out of a sample of us 600 computer chips were defective.
If the company makes three 36000 i.e. (36000 × 3) = 108000 computer chips in a year, then we have to find how many of those will be expected to be defective.
The expected number of defective chips per year will be
