Can someone check number 4 and do the blank ones and explain them, i really need help and don’t know what i’m doing

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

Which is the value of this expression when p=3 and q=-9

Radials are weird[tex](14 \sqrt{6}) ^{2} [/tex]whats the answer and how do i solve pls
