The work of a student to solve the equation 4(2x βˆ’ 4) = 8 + 2x + 8 is shown below: Step 1: 4(2x βˆ’ 4) = 8 + 2x + 8
Step 2: 6x βˆ’ 8 = 16 + 2x
Step 3: 6x βˆ’ 2x = 16 + 8
Step 4: 4x = 24
Step 5: x = 6

In which step did the student first make an error and what is the correct step?

A). Step 2; 8x βˆ’ 4 = 2(6 + x + 6)

B). Step 2; 8x βˆ’ 16 = 16 + 2x

C). Step 3; 6x βˆ’ 2x = 16 βˆ’ 8

D). Step 3; 6x + 2x = 16 + 8

When you dilate a figure with a scale factor of 1/2, what will the dilated figure look like?                                                                                           a: the dilated figure will have side lengths that are half the length of the original side lengths.                                                                          b: the angles in the dilated figure will be half the measure of the original figure.                                                                                c: the dilated figure will have side lengths twice the length of the original.
