Answer:
(3x-5)*(3x-5)
Step-by-step explanation:
Perfect square trinomial is defined by the follow way

Now we can rewrite
as
because a squared add is equal to multiply the add by itself one time
if we make a=3x and b=-5 we can see tha the first answer is the only option that could be a perfect square triomial
Answer: 25
Step-by-step explanation:
From the question, we are told that a producer of electronic book readers is performing a quality check to make sure that the reader's backlight is working correctly. Then, the plant manager tests 2,000 readers on Monday and finds that 8 have defective backlights. The fraction 1/x is the experimental probability of a book reader having a defective backlight. What is the value of x?
Number of tested readers= 2000
Defective backlight = 8
Probability of having a defective backlight will be the number of defective backlight divided by the number of readers tested. This will be:
= 8/200
We reduce the nice fraction to its lowest term.
8/200 = 1/25
Therefore x will be 25
