The product of two numbers is 240. The first number is 8 less than the second number. Which equation can be used to find x, the lesser number?

x(x – 8) = 240
x(x + 8) = 240
x2 – 8 = 240
x2 + 8 = 240

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
