I have a couple of problems I cannot figure out. Any help would be greatly appreciated!
1. Solve the inequality |3x-1|> 4. Express your answer in terms of intervals
2. A piece of wire 40 cm. long is cut into 2 pieces. One piece is bent into a square, the other is bent into an equilateral triangle. Express the length, s, of the side of the square in terms of the length, t, of the side of the triangle.
x = 4s or s = x/4.
Since the whole piece of wire is 40cm and the piece bent into a square is x cm, the piece bent into an equilateral triangle would be 40 - x cm. The perimeter of an equilateral triangle is 3t, so 40 - x = 3t. Solve for x:
Plug this into s = x/4:
