The term b^2 / 4a^2 is not added to the left side of the equation, because the term that was added to the right was not either b^2 / 4 a^2.
As you can see the ther b^2 / 4a^2 that appears in the last step of the table is inside a parenthesis, which is preceded by factor a.
Then, you need to apply the distributive property to know the term that you are really adding to the right side, i.e. you need to mulitply b^2 / 4a^2 * a which is b^2 / 4a.
That means that you are really adding b^2 / 4a to the right, so that is the same that you have to add to the left, which is what the last step of the table shows.
That situation is reflected by the statement "<span>The
distributive property needs to be applied to determine the value to add
to the left side of the equation to balance the sides of the equation".</span> That is the answer.
Answer:
Her angular speed (in rev/s) when her arms and one leg open outward is 
Explanation:
Initial moment of inertia when arms and legs in is 
Final moment of inertia when her arms and on leg open outward, 
Initial angular speed 
Let the final angular speed be 
Since external torque on her is zero so we can apply conservation of angular momentum
=>
=>
Thus her angular speed (in rev/s) when her arms and one leg open outward is
1c. The goal of technology is to improve how people live. For example a toothbrush helps prevent cavities and buildup on our teeth.
2a. Science and technology both help improve our lives. Science gives us the knowledge we need to create technology.
2b. A human prosthetic is an example of technology.
2c. Prosthetics are created though scientific study and research. Technology is used to create the material prosthetics are made of and to help design the prosthetics.
3a. Benefits of pesticides: Keeps bugs away from crops, higher crop yields.
Negatives:
pollution, harmful to health
I got all of them except the last one

Explanation:
Experiments needs to be as accurate and precise as possible. Accuracy and precision helps to keep errors within reasonable limits as they are unavoidable.
How do can we now obtain an accurate and precise result?
After checking that all sources of errors are kept at bay and the procedures perfectly matches the hypothesis being test, it is best to repeat the experiment a few number of times.
Repeating an experiment is scientifically permitted as it helps to eliminate error to a reasonable extent.
Repeating an experiment will also help to authenticate Mitchell's claim and provide a confidence limit to draw a sound conclusion from.
From the repeated results, some statistical parameters that further provide solid backing for the hypothesis being tested will surface.
One of the key attribute of a hypothesis to be acceptable as being valid is that it must be repeatable.
