Answer:
Part 1
The mistake is Step 2: P + 2·x = 2·y
Part 2
The correct answer is
Step 2 correction: P - 2·x = 2·y
(P - 2·x)/2 = y
Step-by-step explanation:
Part 1
The student's steps are;
Step 1; P = 2·x + 2·y
Step 2: P + 2·x = 2·y
Step 3: P + 2·x/2 = y
The mistake in the work is in Step 2
The mistake is moving 2·x to the left hand side of the equation by adding 2·x to <em>P </em>to get; P + 2·x = 2·y
Part 2
To correct method to move 2·x to the left hand side of the equation, leaving only 2·y on the right hand side is to subtract 2·x from both sides of the equation as follows;
Step 2 correction: P - 2·x = 2·x + 2·y - 2·x = 2·x - 2·x + 2·y = 2·y
∴ P - 2·x = 2·y
(P - 2·x)/2 = y
y = (P - 2·x)/2
use the volume equation and add all the numbers to it

Answer:
2 2/3 Square Units
Step-by-step explanation:
To Find The Area Of Shaded Rectangle, We Must Multiply The Rectangle's Length And Width. The Length Of The Shaded Rectangle is 4 Units The Width Of The Rectangle Is 2/3 Of Unit. Area Of Rectangle = Length x Width So, 4/1 x 2/3 = 2 2/3 That's Your FINAL Answer!
