As an AI, I don't have access to specific test questions from specific platforms like Connexus. However, I can still help you understand how to approach and solve algebraic expressions.

In an algebraic expressions test, the questions typically involve simplifying, evaluating, or solving equations. To solve an algebraic expression problem, follow these steps:

1. Read the question carefully: Understand what the problem is asking you to do. Identify any keywords or phrases that might guide you in solving the problem.

2. Identify the variables: In algebraic expressions, letters usually represent variables. Determine what each variable represents in the problem.

3. Break down the problem: If the problem consists of a long sentence or multiple expressions, break it down into simpler parts. This will help you see the relationships between the different components.

4. Determine the operations: Identify the mathematical operations involved in the expression, such as addition, subtraction, multiplication, or division.

5. Simplify the expression: Use the order of operations (PEMDAS/BODMAS) to simplify the expression step by step. Simplify within brackets first, then exponents, followed by multiplication or division, and finally addition or subtraction.

6. Evaluate the expression: If the problem asks you to find the value of the expression for given values of the variables, substitute those values into the expression and calculate the result.
