Deep Dive: Solving Specific Problems from Practice Set 71, Part 2

Alright, guys, let’s get down to the nitty-gritty and tackle some specific examples from Practice Set 71, Part 2. Since I can't access a specific practice set, I'll provide example problems that are common in this kind of set, along with detailed explanations. Keep in mind that the exact problems will vary depending on your textbook, but these examples will give you a solid foundation. Let’s dive in and solve some example problems!

Example Problem 1: Algebraic Equations

Problem: Solve for x: 2(x + 3) – 5 = 7

Solution:

1. Distribute: First, distribute the 2 across the terms inside the parentheses: 2x + 6 – 5 = 7.
2. Simplify: Combine like terms: 2x + 1 = 7.
3. Isolate x: Subtract 1 from both sides: 2x = 6.
4. Solve for x: Divide both sides by 2: x = 3.

Explanation: This problem tests your ability to manipulate algebraic equations. You needed to use the distributive property, combine like terms, and isolate the variable (x) to find the solution. Remember to always double-check your work to ensure your calculations are accurate.

Example Problem 2: Geometric Shapes

Problem: A triangle has a base of 10 cm and a height of 8 cm. Calculate its area.

Solution:

1. Recall the formula: Area of a triangle = 0.5 * base * height.
2. Substitute the values: Area = 0.5 * 10 cm * 8 cm.
3. Calculate: Area = 40 cm².

Explanation: This is a straightforward application of the area formula. Understanding the properties of shapes and knowing the correct formulas are essential. In geometry problems, drawing a diagram can help you visualize the problem and understand the given information more effectively. Always include the units in your final answer.

Example Problem 3: Exponents and Radicals

Problem: Simplify: √25 + 3²

Solution:

1. Evaluate the square root: √25 = 5.
2. Evaluate the exponent: 3² = 9.
3. Add: 5 + 9 = 14.

Explanation: The problem tests your understanding of exponents and square roots. Following the order of operations (PEMDAS/BODMAS) is crucial. Always make sure to evaluate exponents and radicals before performing addition or subtraction. Make sure you're confident with these basics, since they often form the groundwork for more complex questions.
