Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
![### Completing the Square to Solve an Equation
#### Fill in the blank so that the resulting statement is true:
To solve \( x^2 - \frac{4}{11}x = \frac{16}{121} \) by completing the square, add [blank] to both sides of the equation.
(Type an integer or a simplified fraction.)
In order to complete the square for the equation \( x^2 - \frac{4}{11}x = \frac{16}{121} \), we need to find a value that makes the left-hand side of the equation a perfect square trinomial.
1. Take the coefficient of \( x \), which is \( -\frac{4}{11} \).
2. Divide it by 2:
\[ -\frac{4}{11} \div 2 = -\frac{2}{11} \]
3. Square the result:
\[ \left(-\frac{2}{11}\right)^2 = \frac{4}{121} \]
So, we need to add \( \frac{4}{121} \) to both sides of the equation.
Therefore, the blank should be filled with:
\[ \boxed{\frac{4}{121}} \]
By adding \( \frac{4}{121} \) to both sides, the equation becomes:
\[ x^2 - \frac{4}{11}x + \frac{4}{121} = \frac{16}{121} + \frac{4}{121} \]
\[ \left( x - \frac{2}{11} \right)^2 = \frac{20}{121} \]
This completes the square and simplifies solving the equation.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F12b4d682-ca36-49f4-9f62-65ddd961264e%2F7c69b968-622d-4794-8252-90c2f3093171%2Fi4keah_processed.jpeg&w=3840&q=75)
