Hank made a mistake in Step 1. The equation he started with was \(25 = x^4 - 9\). To isolate \(x^4\), he should have added 9 to both sides, resulting in \(25 + 9 = x^4\) or \(34 = x^4\). Instead, he subtracted 9, which is incorrect. The correct first step is to add 9 to both sides of the equation.
Hank's work to solve the equation 25=x4−925=x4−9 is shown below. In which step did Hank make a mistake, and what mistake did he make? 25=x4−925=x4−9 Step 1: 16=x416=x4 Step 2: x=64x=64 (1 point) Responses Hank made a mistake in Step 1. The first step needed to solve this correctly would be to add 9 to both sides of the equation. Hank subtracted 9 instead of adding 9. Hank made a mistake in Step 1. The first step needed to solve this correctly would be to add 9 to both sides of the equation. Hank subtracted 9 instead of adding 9. Hank made a mistake in Step 1. The first step needed to solve this correctly would be to multiply both sides of the equation by 4. Hank divided by 4 instead of multiplying. Hank made a mistake in Step 1. The first step needed to solve this correctly would be to multiply both sides of the equation by 4. Hank divided by 4 instead of multiplying. Hank made a mistake in Step 2. The second step needed to solve this correctly would be to divide both sides of the equation by 4. Hank multiplied by 4 instead of dividing. Hank made a mistake in Step 2. The second step needed to solve this correctly would be to divide both sides of the equation by 4. Hank multiplied by 4 instead of dividing. Hank made a mistake in Step 2. The second step needed to solve this correctly would be to subtract 9 to both sides of the equation. Hank added 9 instead of subtracting 9.

The correct first step to solve the equation \(14k + 23 = 17\) for \(k\) is to subtract 23 from both sides of the equation.
This gives you:
\[ 14k + 23 - 23 = 17 - 23 \]
or
\[ 14k = -6 \]
From there, you can proceed to solve for \(k\).
