Hank is working on simplifying the algebraic expression 4x−14 when x=5 . Her steps are as follows: Step 1: 45−14 Step 2: 20−14 Step 3: 6 In which step did Jenny make a mistake? What should she have done differently? (1 point) Responses

Answer 1

Hank made a mistake in Step 1.

In Step 1, she incorrectly calculated \( 4x \) as \( 45 \) instead of correctly substituting \( x = 5 \) into the expression \( 4x - 14 \).

The correct calculation should have been:

Step 1: Substitute \( x = 5 \) into the expression: \[ 4(5) - 14 \]

This results in: \[ 20 - 14 \]

Then for Step 2: \[ 20 - 14 = 6 \]

So, the correct answer is that Hank should have calculated \( 4(5) = 20 \) in Step 1, not \( 45 \).
