Answer:
x-4y = 8
Step-by-step explanation:
y– 1 =1/4 (x – 12)
Multiply each side by 4
4y -4 = x-12
Subtract x from each side
-x +4y -4 = -12
Add 4 to each side
-x+4y -4+4 = -12 +4
-x+4y = -8
Multiply by -1
x-4y = 8

Answer:
Step-by-step explanation:
Let L represent the Length of the rectangle.
Let W represent the width of the rectangle.
The formula for determining the perimeter of a rectangle is expressed as
Perimeter = 2(L + W)
Then substitute 12 in for the length and 6in for the width. It becomes.
Perimeter = 2(12 + 6).
Perimeter =2 × 18 = 36
