The work of a student to solve the equation 3(2x - 4) = 8 + 2x + 6 is shown below:

Step 1: 3(2x - 4) = 8 + 2x + 6
Step 2: 5x-7 = 14 + 2x
Step 3: 5x - 2x= 14 + 7
Step 4:3x = 21
Step 5: X= 7

In which step did the student first make an error and what is the correct step? (5 points)
Step 2: 6x - 12 - 14 - 2x
Step 2: 6x - 7 = 246 + x + 4)
Step 3: 5x-2x = 14-7
Step 3: 5x + 2x = 14 + 7

Arectangle is a quadrilateral and a parallelogram.here is all that apply to a rectangle!

First locate the turning point (vertex) of the graph. which is at the coordinates x=5 and y=9 or (5; 9).to determine whether it's a maximum or mininum value, you have to discern whether the vertex's y-value is the highest value or lowest value the graph can reach. since the vertex's y-value, 9 is the highest value the graph can reach, it will be a maximum.another basic way to determine whether the vertex's value is max or min is to see if the graph is smiling or sad. if it's smiling, the turning point/vertex would be a minimum, while a sad parabola would have a maximum y-value at the vertex.
