Answer:

The answer is 23.

Explanation:

You square the 1st expression and you will get the 2nd expression :

{(x + \frac{1}{x}) }^{2} = {5}^{2}

{x}^{2} + 2(x)( \frac{1}{x}) + { (\frac{1}{x}) }^{2} = 25

{x}^{2} + 2 + \frac{1}{{x}^{2}} = 25

{x}^{2} + \frac{1}{{x}^{2}} = 23

Answer:

23

Explanation:

Use: $(a+b)^2= a^2+2 ab+b^2$

Square both sides:

\Big( x+\frac{1}{x}\Big)^2=5^2\\\implies x^2+2(x) \Big(\frac{1}{x}\Big) +\frac{1}{x^2}=25\\\implies x^2+\frac{1}{x^2}=25-2=\boxed {\color{red}{23}}

Marizza181 [45]

Answer:

* Glucose may cause an increase in bacterial growth - HYPOTHESIS

* The bacterial colonies grown without glucose don’t have capsules around their cells - OBSERVATION

* Bacterial growth in the glucose environment increased rapidly and then stopped after some time - OBSERVATION

* Increased glucose may lead to capsule formation in bacteria - HYPOTHESIS

Explanation:

In an experiment, a HYPOTHESIS is a predictive and testable statement that aims to answer a scientific question while an observation is made based on the results obtained.

According to this question, Annie wants to study the effect of glucose on bacterial colonies. She conducted the experiment by growing two colonies of bacteria - one with glucose present in the environment and one in an environment without glucose. Based on this experiment, the following statements are categorized as:

- Glucose may cause an increase in bacterial growth is a HYPOTHESIS

- The bacterial colonies grown without glucose don’t have capsules around their cells is an OBSERVATION

- Bacterial growth in the glucose environment increased rapidly and then stopped after some time is an OBSERVATION

- Increased glucose may lead to capsule formation in bacteria is a HYPOTHESIS
