Alanna tried to solve an equation step by step. \begin{aligned} 4c&=12 \dfrac{4c}{4}&=12\cdot4&\gr een{\text{Step } 1} c&=48&\blue{\text{Step } 2} \end{aligned} 4c 4 4c c =12 =12⋅4 =48 Step 1 Step 2 Find Alanna's mistake.

Her mistake was in step 1

Step-by-step explanation:

Given the expression solved by Alanna

4c = 12

To get c, we will divide both sides of the equation by 4:

4c/4 = 12/4

c = 12/4

c = 3

Alanna made mistake in step 1 where she divided multiplied the right hand side of the equation by 4 instead of dividing by 4

square root of 36/6 = 2.449489743

square root of 16/6 = 1.632993162

square root of 6 = 2.449489743

the answer is square root of 16/6 because the square root of 36/6 is the same answer as square root of 6 = 2.449489743
