The Importance of Answer Keys in Education
Answer keys play a vital role in the educational experience for several reasons:
1. Self-Assessment
- Answer keys allow students to check their work independently.
- They help learners identify areas of strength and weakness.
- By comparing their answers to the provided key, students can gauge their understanding of the material.
2. Immediate Feedback
- Students receive prompt feedback on their homework, which is crucial for learning.
- Instant feedback helps reinforce concepts and rectify misunderstandings before moving on to new material.
3. Study Aid
- Answer keys can serve as a study tool for upcoming tests and quizzes.
- They allow students to revisit challenging topics and practice similar problems.
4. Teacher Resource
- Educators can use answer keys to evaluate student performance quickly.
- They help in identifying common errors among students, allowing teachers to address these in class.

Lesson 7 Homework 45 Answer Key Breakdown
Here, we will provide a detailed answer key for Lesson 7 Homework 45, including sample problems and explanations for each answer.
Sample Problems and Answers
Problem 1: Solve for x in the equation \(2x + 3 = 11\).
- Solution:
1. Subtract 3 from both sides: \(2x = 8\)
2. Divide both sides by 2: \(x = 4\)
- Answer: \(x = 4\)
Problem 2: Simplify the expression \(4a + 2a - 3a\).
- Solution:
1. Combine like terms: \(4a + 2a - 3a = (4 + 2 - 3)a\)
2. Simplify: \(3a\)
- Answer: \(3a\)
Problem 3: Graph the equation \(y = 2x + 1\) using the slope-intercept method.
- Solution:
1. Identify the slope (m) and y-intercept (b): \(m = 2\), \(b = 1\)
2. Start at \(b = 1\) on the y-axis.
3. From there, use the slope to find another point: up 2 units and right 1 unit.
4. Plot the points and draw a line through them.
- Answer: The graph should show a straight line that crosses the y-axis at (0, 1) and rises steeply.
Problem 4: Calculate the area of a rectangle with a length of 5 units and a width of 3 units.
- Solution:
1. Use the formula for area: \(Area = length \times width\)
2. Substitute the values: \(Area = 5 \times 3 = 15\)
- Answer: Area = 15 square units.
Problem 5: Identify the type of angle that measures 90 degrees.
- Solution: A 90-degree angle is called a right angle.
- Answer: Right angle.
