Evaluate the Expressions for x = 2
What are the expressions that need to be evaluated for x = 2?
–9.2(4 – x)
-36.8 + 9.2x
Expressions to Evaluate:
For x = 2, we need to evaluate the expressions –9.2(4 – 2) and -36.8 + 9.2x.
When x = 2, we can simplify the expressions as follows:
Simplification process:
- -9.2(4 – x) becomes -9.2(4 – 2) which simplifies to -9.2(2). Calculating this results in -9.2 * 2 = -18.4.
- -36.8 + 9.2x becomes -36.8 + 9.2*2 when x = 2. Simplifying, we get -36.8 + 18.4, which equals -18.4.
Equivalent Expressions:
For x = 2, the expressions -9.2(2) and -36.8 + 9.2x are equivalent, both evaluating to -18.4.
Therefore, after simplification, we find that these two expressions are equivalent when x = 2.
