The work of a student to solve the equation 2(4x – 4) = 8 + 4x + 4 is shown below: step 1. 2(4x – 4) = 8 + 4x + 4 step 2. 6x – 6 = 12 + 4x step 3. 6x – 4x = 12 + 6 step 4. 2x = 18 step 5. x = 9 in which step did the student first make an error and what is the correct step? step 2,8x – 6 = 2(6 + 2x + 2) step 2,8x – 8 = 12 + 4x step 3,6x – 4x = 12 – 6 step 3,6x + 4x = 12 + 6

1) The step 2 is wrong.

2) the correct step is  8x - 8 = 12 + 4x

Step-by-step explanation:

2(4x – 4) = 8 + 4x + 4

Step 1. :

= 2(4x – 4) = 8 + 4x + 4

Step 2. :

=6x – 6 = 12 + 4x ( wrong)

This was wrong because , 2 multiplied by 4 is 8 not 6.

The correct way:

Step 1. :

2(4x – 4) = 8 + 4x + 4

Step 2. :

Step 3. :

Step 4. :

Step 5. :

12m

step-by-step explanation:

square root means have of a number so have of 3 is 1.5 then multiply it by 8 and you get your answer!

0.038
