Please help me I only have 10 minutes I’m begging you please

Two variables, x and y, vary inversely, and x=12 when y=4. what is the value of y when x=3?

Solve each quadratic equation by factoring and using the zero product property. 10x + 6 = -2x^2 -2

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
