It seems you are looking for help with evaluating algebraic expressions based on a specific lesson in a practice unit. However, without the specific algebraic expressions or the problems from "Unit 6 Lesson 2," I can only provide general guidelines on how to evaluate algebraic expressions.
To evaluate an algebraic expression, follow these steps:
- Substitute the values: Replace the variables in the expression with the given numbers.
- Perform operations: Follow the order of operations (PEMDAS/BODMAS):
- Parentheses/Brackets first
- Exponents/Orders (i.e., powers and square roots, etc.)
- Multiplication and Division from left to right
- Addition and Subtraction from left to right
- Simplify the expression: Carry out the calculations to arrive at the final answer.
Example Problem
Let's say the expression is \( 2x + 3y \) and you need to evaluate it for \( x = 3 \) and \( y = 4 \):
-
Substitute the values: \[ 2(3) + 3(4) \]
-
Perform the operations: \[ 6 + 12 = 18 \]
So the evaluated expression equals 18.
