No not enough sugar I have 2 1/2 is more than 2 1/3 For 1/2 (0.5) is more than 1/3 (0.333) 1/2 - 1/3 = 3/6 - 2/6 = <u>1/6 </u>So we still need 1/6 of a cup of sugar
Look at W and W'. W is (-2, -1), but W' says (-4, -2). 2 x 2 is 4 and 1 x 2 is 2. Both coordinates were multiplied by 2. The same goes for all the other vertices, so it would be k = 2.
