PTS:126.ANS: CArrange the tiles into a rectangle:So PTS:127.ANS: CArrange the tiles into a rectangle:So PTS:128.ANS: CThe expression has a common factor of 3x. 3x must multiply by 3x and by -2 to give .PTS:129.ANS: AArrange the tiles into a rectangle:

So PTS:130.ANS: CArrange the tiles into a rectangle:So PTS:131.ANS: AWe can think of this multiplication using tiles ... but it is not necessary to draw the tiles every time. The following diagram illustrates the multiplication (as long as you understand that 3x multiplied by x is 3x.) or...
