Answer:
The porch is 17 ft by 17 ft
Step-by-step explanation:
The perimeter of a square is
P = 4s where s is the side length
P = 4( 3x+2)
P = 12x+8
We know P = 14x-2
14x-2 = 12x+8
Subtract 12x from each side
14x-2 -12x = 12x+8-12x
2x -2 = 8
Add 2 to each side
2x-2 +2 = 8+2
2x= 10
Divide by 2
2x/2 = 10/2
x = 5
The side is 3x+2
3*5+2
15+2
17

15/5 = 3
Flour = 3/8 x 3 = 9/8 = 1 1/8 cups.
Chocolate chips = 1/2 x 3= 3/2 = 1 1/2 cups.
Butter = 4/5 x 3 = 12/5 = 2 2/5 cups.
Teaspoons of salt = 4/16 = 1/4 = 1/4 x 3 = 3/4
Earthworms = 1.5 = 3/2 x 3 = 9/2 = 4 1/2 cups.
