Perimeter = length + length + width + width
P= (x + 2) + (x + 2) + x + x
P = x + 2 + x + 2 x + x
P= 4x + 4
Some teachers then want you to pull out the common factor of 4. If yours does, it’s P = 4(x + 1)
Answer:
x = 70
Step-by-step explanation:
Step 1: Simplify both sides of the equations.
Step 2: Subtract 5/7x from both sides.
Step 3: Multiply both sides by 70/(-43).
Step 4: Check if solution is correct.
Therefore, x = 70.
