17. find the value of x
18. find the area of each
19. find the surface area of each figure round to the nearest tenth.
20. find the volume of each figure

One line passes through (-7,-4) and (5,4) . another line passes through the point (-4,6) and (6,-9)

Is the point (0, 8) on the x-axis or y-axis? how do you know?

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
