Veronica's mom left 3/4 of a cake on the table. her brothers ate 1/2 of it. what fraction of the cake did the eat?

Don't know how to find x given these segment lengths

Scenario: susan wants to make 2 square flags to sell at a crafts fair. the fabric she wants to buy is 3 meters wide. she doesn't want any fabric left over. what's the least amount of fabric she should buy? question: which equation will susan solve her problem? note: let x represent the length of 1 side of the flag. options: 1) 2x^2 = 4x 2) 8 +2x = 2(4x) 3) 2 * 2 = 4 * 2 4) 4x^2 -2x = 0

The triangles are similar. what is the value of x? enter your answer in the box.
